refactor(tests): phase 3, move invocationcount, parameters and inheritance to org.testng.*#3499krmahadevan wants to merge 10 commits into
Conversation
One file can carry many descriptions. ParameterTest.java carries four and ListenerTest.java seventeen. The commit that created the file says nothing about a description added to it years later, so six of nine phase 3 references resolved to the 2021 module split. BY_DESCRIPTION=1 finds the commit that wrote the text instead. It searches every Java file. Restricting the search to one path brings back the same fault, because a rename makes the text look added at the new path. It searches for a regex, not a plain string. "GITHUB-182" is the start of "GITHUB-1827", and a plain string answered issue 182 with the commit that wrote GITHUB-1827. Issue 299 answered with the one that wrote GITHUB-2991. Ten such pairs exist in the test tree. An earlier phase of this migration may have written a description itself. That commit names no issue, because the proof came from the file. The NOT PROVEN message now says to check the path before removing anything. Six tests cover the mode. Reverting either fix fails them.
…3446 layout Phase 3 of eight: invocationcount, parameters and inheritance. github1417, testng37 and testng387 join their features. testng317 goes to phase 4 and issue107 to phase 8; neither is about these three. FailedInvocationCountTest asserted the order of <include> elements in testng-failed.xml. TestNG collects a class's methods through a hash-based set, so the order follows Method#hashCode(), which includes the class name. Renaming the package changed it and the test failed. It now asserts each element by its method name. Whether that order is meant to be stable is a separate question, and may be worth its own issue. test.testng37.NullParameterTest has never run. Its suite file is loaded by nothing, that file gives an int parameter the string "NULL", and the method asserts isNull() on that int. It moves as it is. The plan says why. CancelledInvocationReportingTest described two methods as GITHUB-3408. That is a pull request. No commit ties the test to an issue, so the prefix is gone and the prose stays. Five descriptions are new: GITHUB-949, GITHUB-980, GITHUB-1417, GITHUB-1719 and GITHUB-2238.

Included review availability: Your plan provides up to 8 included reviews per hour; 7 remain after this review.
BY_DESCRIPTION searched every Java file and took the oldest commit that wrote the text. One issue number often sits in several files: GITHUB-1336 is in six and GITHUB-2830 in five. A file that copied a marker from another test was proven by that other test's commit. The candidate list stays repository wide, because a rename hides the commit otherwise. The answer must now be a commit that added the text to a file of this name. Two tests cover it. The first checks that a second file carrying the same marker is not proof. The second checks the first file still is. The plan said three legacy packages made the difference between 96 files and 90. The table below it lists five. Three stay in phase 3, and the two that leave hold the six files.

I found a few points that I think should be checked before merging:
BY_DESCRIPTIONcurrently searchesGITHUB-<n>across all Java files and takes the first matching commit. This seems able to use an unrelated file as provenance when the same issue reference exists in multiple files. Please verify this case and, if valid, bind the result to the target file's rename/history lineage and add a regression test.- The PR/docs say five new descriptions were added (
GITHUB-949,GITHUB-980,GITHUB-1417,GITHUB-1719,GITHUB-2238), but I could not find them on the current PR head. Please check whether the code or the documentation is out of sync. - The explanation for the phase-3 count changing from 96 to 90 looks inconsistent with the table: the six-file difference appears to come from the two packages moved to later phases, while three legacy packages remain in phase 3.
- The
FailedInvocationCountTestchange looks reasonable to me: checking<include>entries by method name rather than XML order seems better aligned with GITHUB-3180. I did not find a reason to block on that change.
Please verify these observations against the current code, fix the ones that are valid, and for any that are not valid, explain why so we can close them confidently.
docs/test-issue-references.md recorded GITHUB-949, GITHUB-980, GITHUB-1417, GITHUB-1719 and GITHUB-2238 as verified and added. The verification was real. The descriptions never reached the code. The document said the work was done and nothing checked. Each now sits on the registered test that carried none. GITHUB-2238 goes on four methods, because all four are that issue. The same check found five more, from phase 1. GITHUB-565, GITHUB-799, GITHUB-1231, GITHUB-1232 and GITHUB-1490 are recorded but their classes still sit in top-level test.* packages that no phase has moved. Phase 1 proved them by sweeping every class in reach, so the evidence holds, but the description waits for the owning feature. The document now says so in its own section rather than reading as if they are in place.

All three are valid. Thanks. Two of them I had already fixed locally when you reviewed. You saw
The five descriptions. This one you found, and it was the worst of the three. Fixed in I added a check that reads every reference the document records and requires it in the code. Removing one description makes it fail. It runs before the push. That check found five more, from phase 1. The 96 to 90 prose. Right, and it disagreed with the table directly below it. Five legacy packages were counted into phase 3. Three stay. The two that leave hold the six files. One note on CI. The Phases 3 to 8 now have an issue each, linked as sub-issues of #3446. This pull request closes #3493. Each later issue carries the decisions this phase pushed forward, so they are not lost: #3494 owns |
refs-in-sync.sh lived in a local skill directory that git ignores, so the check that caught this gap did not ship and nobody else could run it. It moves to scripts/ and the scripts workflow runs it. The workflow now also fires on docs/test-issue-references.md and on the test sources, because the check compares those two. Its job is named issue-references, since it runs two checks about them rather than one script. The check asks whether a reference the document records is in the code at all. It does not count the methods that carry one. GITHUB-2238 sits on four, and dropping one of them still passes. The document records which issue a test covers, not how many of its methods say so.

Thanks for the latest updates. The previous documentation/description issues are fixed, the new consistency check is now part of CI, and the latest checks are green.
I still see two points that I think should be verified before merging:
BY_DESCRIPTIONnow restricts candidates usingbasename "$frag", but that still does not identify the actual file lineage. Two unrelated files such asa/IssueTest.javaandb/IssueTest.javacan match the same"*/IssueTest.java"pathspec, so one may still provide provenance for the other. Please verify this with a same-basename regression test.refs-in-sync.shcurrently checks forGITHUB-<n>anywhere under the test sources. A comment, string literal, or unrelated annotation could therefore satisfy the check even when the documented@Test(description = "GITHUB-<n>")is missing. Please verify this with a negative test containing only a non-description occurrence.
If these observations are valid, please fix them and add the corresponding regression coverage. If either is not valid, please explain what prevents the false positive.
Two false positives, both reported on the pull request. BY_DESCRIPTION bound the answer to the file's name. A name is not a file: 45 files here are called IssueTest.java and 60 TestClassSample.java. Asking about GITHUB-1719 in invocationcount/issue1719/IssueTest.java reported that it was written in issue2238/IssueTest.java as well. The binding is now the file's history. --follow gives every path this one file has had, and a commit counts only if it wrote the text to one of them. refs-in-sync.sh accepted GITHUB-<n> anywhere under the test sources, so a comment, a javadoc line or a bare string literal satisfied a document row while no @test carried the description. It now looks for the reference inside a description attribute, over a window of three lines, because a description often spans them. scripts/test/refs-in-sync-test.sh covers that check for the first time: eight cases, including a comment, a javadoc line, a bare string, a longer number, and a description written over three lines. Matching anywhere again fails three of them. Three more tests cover the file binding. Two files of the same name no longer prove each other, and a path the file came from still counts.
|
Both are valid. Fixed in The basename bound nothing. Worse than you described. I asked about The binding is now the file's history rather than its name. Three tests cover it: two files of the same name do not prove each other, the first of the two is still proven, and a path the file came from still counts. A comment satisfied the check. Also right, and CodeRabbit reported it too. I reproduced it by turning It now looks for the reference inside a @Test(
description =
"GITHUB-3408: whether the data provider was parallel ...")
The 29 tests for the verifier, 8 for the sync check. All 14 checks are green. |
The workflow named each test suite by hand. A new script with no test then passed CI in silence. That is how verify-issue-refs.sh and refs-in-sync.sh both shipped, and between them they drew five review points, every one in the untested part. scripts/test/run-all.sh discovers the suites instead. It fails when scripts/x.sh has no scripts/test/x-test.sh, and runs every suite it finds. Adding a script without a test fails it. So does a suite that breaks. A script here decides whether a reference may be written into the code. A wrong answer is silent, which is why the rule is a build failure rather than a line in a document.
|
One more change, Both scripts here shipped with no tests. The workflow named each suite by hand, so a script with no test passed CI in silence. Every point you raised about the tooling was in the untested part.
These scripts decide whether an issue reference may be written into the code. A wrong answer is silent. So the rule is a build failure rather than a note in a document. One thing this does not fix. A gate stops an untested script. It does not make me think of the right rejection cases. You thought of two files sharing a basename and I did not. That part is still your job, and this pull request is the evidence for it. All 14 checks are green. |

Thanks for the additional changes and the explanation. I rechecked the current head. The previous file-lineage fixes look good and all CI checks are now green.
I still see a few points that I think should be verified:
GITHUB-3408is documented in both the PR anddocs/test-issue-references.mdas removed because #3408 is a pull request, but bothCancelledInvocationReportingTestmethods still carry it. The base already contained these descriptions and the PR diff only moves the class. Please verify whether the removal was missed; if so, remove the prefix while keeping the prose as documented.refs-in-sync.shcurrently extracts every backtickedGITHUB-*before the “description not yet written” heading. That also includesGITHUB-3408in the prose explaining that it was removed. As a result, actually removing it from the code would make the sync check fail. Please verify and, if valid, make the parser distinguish references that are asserted by the document from references merely discussed as removed/rejected.waitingis collected from the “Verified, description not yet written” heading to EOF. This currently captures later prose such asGITHUB-521, so a reference that is actually required earlier in the document can become accidentally exempt from the check. Please verify that the exemption is scoped to the intended table/section only.- The remaining CodeRabbit concern also looks valid:
has_description()checks for a nearbydescription =, but does not actually establish that it belongs to a TestNG@Testannotation. A field/string or another annotation with adescriptionattribute could still satisfy the check. Please verify this with a negative regression case and tighten it if needed. run-all.shwas manually checked for both an untested script and a failing suite, which is good. Please consider whether those two behaviors should also have persistent regression coverage, since this script is now the CI gate that guarantees the other scripts are tested.
Please verify each point against the intended contract, fix the ones that are relevant, and for any that are not, explain why the apparent false-positive/false-negative case cannot occur.
…eason The document, the commit message and the pull request all said GITHUB-3408 was removed because testng-team#3408 names a pull request. Both descriptions still carried it. The removal never happened, and the check that should have caught it was broken in three ways at once. It read every backticked reference in the document, so the sentence explaining that GITHUB-3408 was dropped counted as a claim that the code must carry it. Removing the reference would have failed the check. It now reads table rows only. Prose is not a claim. The exemption for references whose class has not moved ran from its heading to end of file, so later prose exempted GITHUB-521 by accident. It is scoped to its own table now. A description was enough on its own. @dataProvider takes one too, and a field may be called description, so neither was the code claiming anything. Both @test and description must now sit in the window. While fixing that last one I found the check had been passing for no reason at all. The headings were read with a for loop, and a heading has spaces, so word splitting left the required set empty. It reads them one line at a time now. run-all.sh guards the other scripts and had no tests of its own. Six cases cover it: a script with no suite, a failing suite, one passing suite not hiding another, an empty tree, and a suite with no script. 47 tests across three suites. Each fix fails its tests when reverted.
|
All five are valid. Fixed in
The prose was read as a claim. The check pulled every backticked reference before the exemption heading, including the sentence explaining that The exemption leaked past its table. It ran from its heading to end of file and swallowed A description was not enough. It accepted The gate had no tests. You are right that it is the wrong script to trust by hand. Six cases now: a script with no suite, a failing suite, one passing suite not hiding another, an empty tree, and a suite with no script of its own. One you did not raise, and it is worse than the five. While fixing the fourth point I found the check had been passing for no reason at all. I read the section headings with a 47 tests across three suites. Each fix fails its tests when reverted. Two things worth saying about the shape of this, rather than the individual points. The gate I added yesterday would not have caught any of these five. They are wrong logic inside scripts that already had tests, not missing test files. So it helps and it is not the answer. Three of the four faults in All 14 checks are green. |

Thanks for the latest update. I rechecked abfb0c1: the previous findings are addressed, the new regression coverage is useful, and all CI checks are green.
I still see one remaining edge case around refs-in-sync.sh that should be verified:
has_description()currently accepts a match when@Test,description =, andGITHUB-<n>occur anywhere within the same four-line window, but it does not prove that thedescriptionbelongs to that@Testannotation. For example, an@Testimmediately followed by@DataProvider(description = "GITHUB-765")could still satisfy the check. The new tests cover a standalone@DataProviderand a standalonedescriptionfield, but not this mixed-window case. This is also the remaining part of CodeRabbit's original concern.
Please verify this case and tighten/add regression coverage if it is valid. If the current implementation cannot produce this false positive, please explain why.
Everything else I previously raised looks resolved on the current head.
has_description checked that @test, description and the reference all appeared within four lines. That is a weaker claim than the document makes. An @test followed by @dataProvider(description = "GITHUB-765") satisfied it, and so did an @test method with a data provider further down the class. It now reads the annotation. It tracks the parentheses of @test( and collects the text until they close. A bare @test opens nothing and carries no description, and any other annotation sits outside that text. Four tests cover the shapes that must be rejected: a bare @test above a data provider, an @test method above one, an @test with its own members above one, and a description beside other members of the same @test, which must still be accepted. Going back to the window fails three. This is the third fault of one kind in this script. It matched a marker anywhere, then read prose as a table row, and now matched a window rather than the annotation. Each time it tested text against a pattern where it should have read the structure.
The script had no stated contract, so each review round found a case it did not cover and I patched the pattern. Four rounds went that way. It answers one question: does a description this document records exist in the code at all. Three things are outside that, and the header says so. It checks one direction. It does not count occurrences. It does not judge whether a description is the right one for its test, which is what verify-issue-refs.sh is for. It is frozen. If a case gets past it, record the case in the header and leave the code alone. The header also names the way out, if a fifth case ever looks worth fixing: move the evidence into a CSV and generate the document from it, rather than patch another pattern. It says plainly what that buys. Two of the four faults came from reading a document written for people, and a CSV removes both. The other two came from reading Java as text, and a CSV does nothing for those.

You are right. I reproduced both shapes. Both passed. The bug: I looked at a window of four lines. If Now it reads the annotation. It counts the brackets of
Four new tests. Going back to the window fails three of them. 51 tests in total. I have also frozen that script and written down what it does. This is the fourth round where you found a gap and I patched a pattern. That is a bad trade now. The header says what it checks: does a description in the document exist in the code. It checks one direction. It does not count how many methods carry one. It does not check that the description is the right one for the test. If a fifth gap turns up, the header asks you to write the case down rather than patch the code. The header also says how to fix it properly, and what that would buy. Two of the four bugs came from reading a document meant for people. A CSV would remove both. The other two came from reading Java as text. A CSV does nothing for those. That needs a real parser, which is more work than the migration itself. One more thing. This script has never caught the problem it was written for. You found the five missing descriptions before it existed. You found All 14 checks are green. |

Thanks for the latest updates. I rechecked the current head: the previous mixed-annotation case is now correctly covered, the other findings from earlier reviews look resolved, and all CI checks are green.
I only see one remaining edge case worth verifying in the new @Test(...) parser:
depth_of()counts parentheses textually, including parentheses inside Java string literals or comments. A valid annotation such as@Test(description = "GITHUB-765: expected (")could therefore leave the parser at the wrong nesting depth and make a real description appear missing. Please verify this case. If it is relevant to the intended contract, I would add a failing regression test first and then fix it (red/green). If this limitation is intentionally accepted as part of the documented/frozen parser scope, please explain that explicitly so the behavior is clear.
Apart from that, I do not see any remaining actionable finding from my previous reviews or the other reviewers.

Fixes #3493.
Phase 3 of eight in #3446. Two commits, in this order.
1.
0b240d08e— prove a description from the commit that wrote itscripts/verify-issue-refs.shdecides whether aGITHUB-<n>reference may be written into a@Testdescription. It found the commit that created the file. One file can carry manydescriptions:
ParameterTest.javacarries four andListenerTest.javaseventeen. The commit thatcreated the file says nothing about a description added to it years later, so six of nine phase 3
references resolved to the 2021 module split.
BY_DESCRIPTION=1finds the commit that wrote the text instead. It searches every Java file.Restricting the search to one path brings back the same fault, because a rename makes the text look
added at the new path.
It searches for a regex, not a plain string.
GITHUB-182is the start ofGITHUB-1827. With aplain string, issue 182 answered with the commit that wrote
GITHUB-1827, and issue 299 with theone that wrote
GITHUB-2991. Ten such pairs exist in the test tree, andGITHUB-182is areference the phase 1 table already records.
Six tests cover the mode. Reverting either fix fails them. 24 tests in total.
2.
88662f5e5— move the packagestest.invocationcount,test.parametersandtest.inheritancemove toorg.testng.*. Executabletests to
org.testng.<feature>, classes handed to TestNG toorg.testng.<feature>.samples.test.github1417andtest.testng37joinparameters.test.testng387joinsinvocationcount.Three things a reviewer should be told, not have to find
FailedInvocationCountTestchanged its assertion. It asserted the order of<include>elements in
testng-failed.xml, by position. TestNG collects a class's methods through ahash-based set, so their order follows
Method#hashCode(), which includes the declaring classname. Renaming the package changed it and the test failed. Proof it was the move, same command on
the same machine:
It now asserts each element by its method name, and counts how often each name appears.
GITHUB-3180 is about the values each method records, so the test still asserts what the issue is
about. A wrong value, a wrong name, or one occurrence moved between two methods each fail it.
I do not know whether that order is meant to be stable. If it is, the
HashSetinClassHelper.getAvailableMethodsExcludingDefaultsis a defect and deserves its own issue. I didnot investigate further. The test is independent of the order either way.
ParameterSampleis registered intestng.xml. The classification rule makes it executable, soit sits in
org.testng.parametersrather than insamples, despite the name. I followed the rulerather than the name.
NullParameterTestmoves as it is and stays dead. It is in no suite file and has never run.Its suite file
testng-37.xmlsat in the source tree, is loaded by nothing, and gives anintparameter the string
"NULL". The method assertsisNull()on thatint, which cannot hold.Fixing it is not relocation work. The class and its suite file move together so the pair stays
visible, and
docs/TEST_RELOCATION_PLAN.mdrecords why.Issue references
Eight existing descriptions verified and kept. Five added:
GITHUB-949,GITHUB-980,GITHUB-1417,GITHUB-1719,GITHUB-2238. Each names a registered test that carried none.One removed.
CancelledInvocationReportingTestdescribed two methods asGITHUB-3408, which is apull request rather than an issue. That pull request says "Part of #3406", but the commit that
wrote the descriptions is not in it, and no commit ties the test to an issue. The prefix is gone
and the prose stays.
docs/test-issue-references.mdrecords all of it. Every row is generated from the GitHub API andfrom git, never typed, after phase 2 shortened four issue titles by hand.
Evidence the phase lost nothing
The execution inventory changed 53 lines. All 53 are renames: same total, no status change, no
count change, nothing added and nothing lost.
