What is the purpose of this PR
Adds a GitHub Actions workflow to confirm the flakiness of
cz.habarta.typescript.generator.TaggedUnionsTest.testTaggedUnionsWithInterfacesin thetypescript-generatorproject, as part of the IDoFT flaky test task (Part Three).Why the test fails
The test likely relies on non-deterministic iteration order (e.g., HashMap keys) in generated TypeScript output, causing intermittent failures when shuffled by NonDex.
How to reproduce the test failure
Run the GitHub Actions workflow in this PR or locally:
mvn -pl typescript-generator-core edu.illinois:nondex-maven-plugin:2.1.1:nondex -Dtest=cz.habarta.typescript.generator.TaggedUnionsTest#testTaggedUnionsWithInterfaces -DnondexRuns=50The test fails intermittently due to order-dependent assertions.
Expected results
The normal test run passes consistently, while the NonDex run fails intermittently, confirming the test is flaky.
Actual results
In the CI run ([link to Actions run, e.g., https://github.com/ndeneh93/typescript-generator/actions/runs/XXXXX]), the normal test passed, and the NonDex test failed X/50 runs, confirming flakiness.
Description of changes
Added
.github/workflows/flaky-test.ymlto run the test normally and with NonDex, verifying its flaky behavior in CI.
