What is the main benefit of parallel test execution?
✗ Incorrect
Running tests at the same time helps finish testing faster.
Which problem can happen if tests share data during parallel execution?
✗ Incorrect
Sharing data can cause tests to interfere and fail even if the code is correct.
Which practice helps avoid issues in parallel testing?
✗ Incorrect
Isolating data and resources keeps tests independent and reliable.
Which tool supports parallel test execution?
✗ Incorrect
JUnit 5 supports running tests in parallel.
Parallel test execution is especially useful when:
✗ Incorrect
Running many tests at once saves time.
