Java Reference
In-Depth Information
The function isTrue(message) tests that the actual value is true , displaying an
optional message if it isn't.
The function isFalse(message) tests that the actual value is false , displaying
an optional message if it isn't.
The function not(predicate) inverts the predicate.
The function isNull(message) tests that the actual value is null , returning the
message if it isn't.
The following example shows how to match regular expressions:
var actual = "JUnit in Action";
assert.that(actual, matches(/in/));
assert.that(actual, not(matches(/out/)));
The example calls the match function first to assert that “in” is in the test string b and
then to check that “out” isn't C .
The assert object contains other useful functions: fail is like the JU nit fail
method. The various mustCall functions check that the tests causing the given func-
tions have or have not been invoked.
In order to run the tests, you'll need an Ant build script. Listing 13.4 is the sample
build script used to run our examples.
