feat: add expect.soft for non-fatal assertions - #300

WalkthroughAdded Priority: ⬇️ Low Merge Risk: 🔵 Low · up to Soft assertions that fail outside an active test may lose their useful assertion details. Preserve the original error when no test reporter is available. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Preserve the original error if no test is running.
base.info() throws when Playwright has no active test. Examples: an expect.soft() call in a global setup module that imports these fixtures, or an unawaited soft assertion that settles after the test ends. In those cases the TestInfo error replaces the ExpectError, so the assertion detail is lost.
Rethrow the original error when the reporter is unavailable.
🛡️ Proposed fallback
setSoftFailureHandler((error) => {
- (base.info() as unknown as SoftFailureReporter)._failWithError(error);
+ let reporter: SoftFailureReporter | undefined;
+ try {
+ reporter = base.info() as unknown as SoftFailureReporter;
+ } catch {
+ debug('no active test for soft assertion failure; rethrowing');
+ throw error;
+ }
+ reporter._failWithError(error);

Summary
Adds
expect.soft()with Playwright semantics: a failed soft assertion is recorded on the test and marks it failed, but execution continues so later assertions still run. Works with.notand custom messages.Changes
expect.ts): generalize the custom-message Proxy intointerceptErrors; addexpect.soft, which swallowsExpectErrorand hands it to a runner hook (setSoftFailureHandler). Without a handler, soft throws like a hard assertion. Reporter step titles readexpect.soft.toBeVisible()/expect.soft.not.toBeHidden().fixtures.ts): install the handler, reporting via the same private_failWithErrorPlaywright's ownexpect.softuses.expect.soft.Testing
