> Introducing waitForCondition function into test cases
> -----------------------------------------------------
>
> Key: HBASE-7384
> URL: https://issues.apache.org/jira/browse/HBASE-7384
> Project: HBase
> Issue Type: Test
> Components: test
> Reporter: Jeffrey Zhong
> Assignee: Jeffrey Zhong
> Labels: test
> Fix For: 0.96.0
>
> Attachments: hbase-7384_1.0.patch, hbase-7384.patch, Waiter.java
>
>
> Recently I'm working on flaky test cases and found we have many places using
> while loop and sleep to wait for a condition to be true. There are several
> issues in existing ways:
> 1) Many similar code doing the same thing
> 2) When time out happens, different errors are reported without explicitly
> indicating a time out situation
> 3) When we want to increase the max timeout value to verify if a test case
> fails due to a not-enough time out value, we have to recompile & redeploy code
> I propose to create a waitForCondition function as a test utility function
> like the following:
> {code}
> public interface WaitCheck {
> public boolean Check() ;
> }
> public boolean waitForCondition(int timeOutInMilliSeconds, int
> checkIntervalInMilliSeconds, WaitCheck s)
> throws InterruptedException {
> int multiplier = 1;
> String multiplierProp = System.getProperty("extremeWaitMultiplier");
> if(multiplierProp != null) {
> multiplier = Integer.parseInt(multiplierProp);
> if(multiplier < 1) {
> LOG.warn(String.format("Invalid extremeWaitMultiplier
> property value:%s. is ignored.", multiplierProp));
> multiplier = 1;
> }
> }
> int timeElapsed = 0;
> while(timeElapsed < timeOutInMilliSeconds * multiplier) {
> if(s.Check()) {
> return true;
> }
> Thread.sleep(checkIntervalInMilliSeconds);
> timeElapsed += checkIntervalInMilliSeconds;
> }
> assertTrue("WaitForCondition failed due to time out(" +
> timeOutInMilliSeconds + " milliseconds expired)",
> false);
> return false;
> }
> {code}
> By doing the above way, there are several advantages:
> 1) Clearly report time out error when such situation happens
> 2) Use System property extremeWaitMultiplier to increase max time out
> dynamically for a quick verification
> 3) Standardize current wait situations
> Pleas let me know what your thoughts on this.
> Thanks,
> -Jeffrey
