public class ExceptionCollector
extends Object

ExceptionCollector is a test utility for executing code blocks, collecting exceptions, and generating a single AssertionError containing any exceptions encountered as suppressed exceptions.

This utility is intended to support soft assertion use cases similar to the SoftAssertions support in AssertJ and the assertAll() support in JUnit Jupiter.

getExceptions

public List<Throwable> getExceptions()

Get the list of exceptions encountered in execute(Executable).

返回:

an unmodifiable copy of the list of exceptions, potentially empty

assertEmpty

public void assertEmpty()
                 throws Exception

Assert that this ExceptionCollector does not contain any exceptions.

If this collector is empty, this method is effectively a no-op.

If this collector contains a single Error or Exception, this method rethrows the error or exception.

If this collector contains a single Throwable, this method throws an AssertionError with the error message of the Throwable and with the Throwable as the cause.

If this collector contains multiple exceptions, this method throws an AssertionError whose message is "Multiple Exceptions (#):" followed by a new line with the error message of each exception separated by a new line, with # replaced with the number of exceptions present. In addition, each exception will be added to the AssertionError as a suppressed exception.

抛出:

Exception
