Public Methods

public static void assertAssignableFrom (Class<?> expected, Class<?> actual)

Added in API level 1

Asserts that class expected is assignable from the class actual. This verifies expected is a parent class or a interface that actual implements.

Parameters
expected Class
actual Class

public static void assertAssignableFrom (Class<?> expected, Object actual)

Added in API level 1

Asserts that the class expected is assignable from the object actual. This verifies expected is a parent class or a interface that actual implements.

Parameters

MatchResult

public static MatchResult assertContainsRegex (String message, String expectedRegex, String actual)

Added in API level 1

Asserts that expectedRegex matches any substring of actual and fails with message if it does not. The Matcher is returned in case the test needs access to any captured groups. Note that you can also use this for a literal string, by wrapping your expected string in quote(String).

Parameters
