Tasks

Making Test Assertions

  • final protected function assertFalse($result, $message) — Assert that a value is `false`, strictly. The test fails if it is not.
  • final protected function assertTrue($result, $message) — Assert that a value is `true`, strictly. The test fails if it is not.
  • final protected function assertEqual($expect, $result, $message) — Assert that two values are equal, strictly. The test fails if they are not.
  • final protected function assertFailure($message) — Assert an unconditional failure. This is just a convenience method that better indicates intent than using dummy values with assertEqual(). This causes test failure.
  • final protected function assertSkipped($message) — End this test by asserting that the test should be skipped for some reason.

Exception Handling

  • final protected function assertException($expected_exception_class, $callable) — This simplest way to assert exceptions are thrown.
  • final protected function tryTestCases($inputs, $expect, $callable, $exception_class) — Straightforward method for writing unit tests which check if some block of code throws an exception. For example, this allows you to test the exception behavior of ##is_a_fruit()## on various inputs:
  • final protected function tryTestCaseMap($map, $callable, $exception_class) — Convenience wrapper around @{method:tryTestCases} for cases where your inputs are scalar. For example:

Hooks for Setup and Teardown

  • protected function willRunTests() — This hook is invoked once, before any tests in this class are run. It gives you an opportunity to perform setup steps for the entire class.
  • protected function didRunTests() — This hook is invoked once, after any tests in this class are run. It gives you an opportunity to perform teardown steps for the entire class.
  • protected function willRunOneTest($test_method_name) — This hook is invoked once per test, before the test method is invoked.
  • protected function didRunOneTest($test_method_name) — This hook is invoked once per test, after the test method is invoked.
  • public function willRunTestCases($test_cases) — This hook is invoked once, before any test cases execute. It gives you an opportunity to perform setup steps for the entire suite of test cases.
  • public function didRunTestCases($test_cases) — This hook is invoked once, after all test cases execute.

Internals

  • final public function __construct() — Construct a new test case. This method is ##final##, use willRunTests() to provide test-wide setup logic.
  • private function failTest($reason) — Mark the currently-running test as a failure.
  • private function passTest($reason) — This was a triumph. I'm making a note here: HUGE SUCCESS.
  • private function skipTest($reason) — Mark the current running test as skipped.
  • final public function run() — Execute the tests in this test case. You should not call this directly; use @{class:PhutilUnitTestEngine} to orchestrate test execution.
  • private function failAssertionWithExpectedValue($expect_description, $actual_result, $message) — Fail an assertion which checks that some result is equal to a specific value, like 'true' or 'false'. This prints a readable error message and fails the current test.

Return

public function getPhobjectClassConstant($key, $byte_limit)
Inherited

Phobject

Read the value of a class constant.

This is the same as just typing self::CONSTANTNAME, but throws a more useful message if the constant is not defined and allows the constant to be limited to a maximum length.

Parameters
string$keyName of the constant.
int|null$byte_limitMaximum number of bytes permitted in the value.
Return
stringValue of the constant.

final protected function assertFalse($result, $message)
Inherited

PhutilTestCase

Assert that a value is false, strictly. The test fails if it is not.

Parameters
wild$resultThe empirically derived value, generated by executing the test.
string$messageA human-readable description of what these values represent, and particularly of what a discrepancy means.
Return
void

final protected function assertTrue($result, $message)
Inherited

PhutilTestCase

Assert that a value is true, strictly. The test fails if it is not.

Parameters
wild$resultThe empirically derived value, generated by executing the test.
string$messageA human-readable description of what these values represent, and particularly of what a discrepancy means.
Return
void

final protected function assertEqual($expect, $result, $message)
Inherited

PhutilTestCase

Assert that two values are equal, strictly. The test fails if they are not.

NOTE: This method uses PHP's strict equality test operator (===) to compare values. This means values and types must be equal, key order must be identical in arrays, and objects must be referentially identical.
Parameters
wild$expectThe theoretically expected value, generated by careful reasoning about the properties of the system.
wild$resultThe empirically derived value, generated by executing the test.
string$messageA human-readable description of what these values represent, and particularly of what a discrepancy means.
Return
void

final protected function assertFailure($message)
Inherited

PhutilTestCase

Assert an unconditional failure. This is just a convenience method that better indicates intent than using dummy values with assertEqual(). This causes test failure.

Parameters
string$messageHuman-readable description of the reason for test failure.
Return
void

final protected function assertSkipped($message)
Inherited

PhutilTestCase

End this test by asserting that the test should be skipped for some reason.

Parameters
string$messageReason for skipping this test.
Return
void

final protected function assertCaught($expect, $actual, $message)
Inherited

This method is not documented.
Parameters
$expect
$actual
$message
Return
wild

final protected function assertException($expected_exception_class, $callable)
Inherited

PhutilTestCase

This simplest way to assert exceptions are thrown.

Parameters
exception$expected_exception_classThe expected exception.
callable$callableThe thing which throws the exception.
Return
void

final protected function tryTestCases($inputs, $expect, $callable, $exception_class)
Inherited

PhutilTestCase

Straightforward method for writing unit tests which check if some block of code throws an exception. For example, this allows you to test the exception behavior of is_a_fruit() on various inputs:

public function testFruit() {
  $this->tryTestCases(
    array(
      'apple is a fruit'    => new Apple(),
      'rock is not a fruit' => new Rock(),
    ),
    array(
      true,
      false,
    ),
    array($this, 'tryIsAFruit'),
    'NotAFruitException');
}

protected function tryIsAFruit($input) {
  is_a_fruit($input);
}
Parameters
map$inputsMap of test case labels to test case inputs.
list$expectList of expected results, true to indicate that the case is expected to succeed and false to indicate that the case is expected to throw.
callable$callableCallback to invoke for each test case.
string$exception_classOptional exception class to catch, defaults to 'Exception'.
Return
void

final protected function tryTestCaseMap($map, $callable, $exception_class)
Inherited

PhutilTestCase

Convenience wrapper around tryTestCases() for cases where your inputs are scalar. For example:

public function testFruit() {
  $this->tryTestCaseMap(
    array(
      'apple' => true,
      'rock'  => false,
    ),
    array($this, 'tryIsAFruit'),
    'NotAFruitException');
}

protected function tryIsAFruit($input) {
  is_a_fruit($input);
}

For cases where your inputs are not scalar, use tryTestCases().

Parameters
map$mapMap of scalar test inputs to expected success (true expects success, false expects an exception).
callable$callableCallback to invoke for each test case.
string$exception_classOptional exception class to catch, defaults to 'Exception'.
