Method Detail

assertThrows

public static <T extends Throwable> T assertThrows(Class<T> expectedThrowable,
                                                   Asserts.JUnitExecutable exec)

Asserts that execution of the supplied executable throws an exception of the expectedType and returns the exception.

This is useful to avoid (and comply with) Error Prone's TestExceptionChecker bug pattern.

If no exception is thrown, or if an exception of a different type is thrown, this method will fail.

If you do not want to perform additional checks on the exception instance, simply ignore the return value.
