Stabilize flaky fault-tolerance build test by waiting for InvocationStat initialization

[Copilot]

The build workflow was failing in sofa-rpc-fault-tolerance due to a flaky assertion in ServiceHorizontalRegulationStrategyTest#testAll. The test assumed InvocationStat exists immediately after a single timeout call, which is not always true under transient startup/connection timing in CI.

• Root-cause alignment

  • testAll could fail when provider connection initialization lagged and InvocationStatFactory.ALL_STATS.get(...) returned null on first check.
  • The failure was timing-sensitive, not a production logic regression.

• Targeted test hardening

  • Replaced one-shot stat lookup with bounded retry logic in the test.
  • Added explicit retry parameters (maxRetryAttempts, retryDelayMillis) for readability and maintainability.
  • Preserved existing behavior assertion that stat entries are eventually cleared after the window rollover.

• Failure diagnostics

  • Upgraded the null assertion to include a descriptive message when retries are exhausted.

InvocationStat invocationStat = waitForInvocationStat(statDimension, maxRetryAttempts, retryDelayMillis);
Assert.assertNotNull("InvocationStat should be available after " + maxRetryAttempts + " retry attempts",
    invocationStat);

private InvocationStat waitForInvocationStat(InvocationStatDimension statDimension, int maxRetryAttempts,
                                             int retryDelayMillis) throws InterruptedException {
    for (int i = 0; i < maxRetryAttempts; i++) {
        try {
            helloService.sayHello("liangen");
        } catch (Exception e) {
            LOGGER.info("超时");
        }
        InvocationStat stat = InvocationStatFactory.ALL_STATS.get(statDimension);
        if (stat != null) {
            return stat;
        }
        if (i < maxRetryAttempts - 1) {
            Thread.sleep(retryDelayMillis);
        }
    }
    return null;
}

Pull request overview

This PR aims to reduce CI flakiness by hardening timing-sensitive integration/unit tests and adjusting build/CI settings so tests behave more deterministically.

Changes:

• Hardened fault-tolerance test ServiceHorizontalRegulationStrategyTest#testAll with bounded waits for transport/stat initialization.
• Improved cleanup and startup stability in several integration/registry tests (consumer unRefer(), Consul startup wait + null-safe teardown).
• Updated build execution and Maven Surefire configuration (Surefire version bump, single-fork config, GitHub Actions workflow consolidation).
