JUnit Custom Rules

JUnit 4.7 introduced the concept of custom rules:

There are a number of built in JUnit rules including TemporaryFolder which helps by clearing up folders after a test has been run:

@Rule
public TemporaryFolder tempFolder = new TemporaryFolder();

There's a full list of built in rules here:

I'm interested in finding out what custom rules are in place where you work or what useful custom rules开发者_如何学Go you currently use?

I used @Rule for repeated test: @Rule: 在JUnit4中利用Rule
