zentol opened a new pull request #8534: [FLINK-12614][yarn] Refactor test to not do assertions in @After methods 
URL: https://github.com/apache/flink/pull/8534
 
 
   Refactors the YARN tests to only execute assertion within `@Test` methods. Previously, assertions were also executed in `@After` methods, which tends to make the output on test failure more difficult to read.
   
   I added a `runTests(Runnable)` method to the `YarnTestBase` which encapsulates the previous `@After` assertions. All existing tests were modified to use this method instead.
   
   As a result the majority of changes in this PR are about indentation and exception signatures.
   
   Additionally,
   * the yarn client is shutdown in `@After`
   * an unused field was removed
   * a timeout was removed from 
   `YARNSessionCapacitySchedulerITCase#testVCoresAreSetCorrectlyAndJobManagerHostnameAreShownInWebInterfaceAndDynamicPropertiesAndYarnApplicationNameAndTaskManagerSlots` so that the timeouts defined in test themselves cause the failure next time.
