This Module implements Test Anything Protocol for Adventure Game Studio. You can read more on it here: testanything.org
An example test file output by this libary may look like:
1..4
ok 1 - Input file opened
not ok 2 - First line of the input valid
ok 3 - Read the rest of the file
not ok 4 - Summarized correctly # TODO Not written yet
The plan tells how many tests will be run, or how many tests have run. It’s a check that the test file hasn’t stopped prematurely. It must appear once, whether at the beginning or end of the output. The plan is usually the first line of TAP output (although in future there may be a version line before it) and it specifies how many test points are to follow. For example,
1..10
means you plan on running 10 tests. This is a safeguard in case your test file dies silently in the middle of its run. The plan is optional but if there is a plan before the test points it must be the first non-diagnostic line output by the test file. In certain instances a test file may not know how many test points it will ultimately be running. In this case the plan can be the last non-diagnostic line in the output. The plan cannot appear in the middle of the output, nor can it appear more than once.
The core of TAP is the test line. A test file prints one test line per test point executed. There must be at least one test line in TAP output. Each test line comprises the following elements:
ok or not ok
This tells whether the test point passed or failed. It must be at the beginning of the line. /^not ok/ indicates a failed test point. /^ok/ is a successful test point. This is the only mandatory part of the line. Note that unlike the Directives below, ok and not ok are case-sensitive.
TAP expects the ok or not ok to be followed by a test point number.
Any text after the test number but before a # is the description of the test point.
ok 42 this is the description of the test
The test point may include a directive, after a hash on the test line. There are currently two directives allowed: TODO and SKIP. Hashes at the beginning of a line are considered comments.
Before running any test, remove any leftover files and from a previous run, by running a clean test.
tap.clean_test()
By default, test is printed to a file named agstest.log on the saved games
directory for the game under test.
If you have a plan, state it before starting out.
tap.plan(3);
Then run the needed tests.
String null_string;
tap.ok(String.IsNullOrEmpty(null_string), "String.IsNullOrEmpty test null string");
tap.ok(String.IsNullOrEmpty(""), "String.IsNullOrEmpty test empty string");
tap.ok(!String.IsNullOrEmpty("with text"), "String.IsNullOrEmpty test non-empty string");
After you are done testing, state it.
tap.done_testing();
void tap.clean_test()
This command removes previously outputed test log files if they exist.
void tap.plan(int n, String skip_reason = 0)
This allows setting a plan, so we know how many tests will be run. Just use it
once for the group of tests following. If you want to start a new test, after
a plan has been set, remember to call tap.done_testing() before.
Alternatively, you can pass NO_PLAN if you have no plan.
If the following tests are to be skipped, pass SKIP_ALL, so all tests until
next plan are skipped. They will still be executed, they just won't output log
or be considered whether they fail or succeed.
void tap.ok(bool condition, String test_name = 0)
This test will succeed if the condition is true, and fail if the condition is false.
void tap.nok(bool condition, String test_name = 0)
This test will succeed if the condition is false, and fail if the condition is true.
void tap.is(String got, String expected, String test_name = 0)
This test will succeed if got and expected matches. If this test fails,
we can have some more diagnostic information since we know both inputs and the
premise they are supposed to match.
void tap.isnt(String got, String expected, String test_name = 0)
This test will succeed if got and expected does not matches. If this test
fails, we can have some more diagnostic information since we know both inputs
and the premise they are not supposed to match.
void tap.is_int(int got, int expected, String test_name = 0)
This test will succeed if got and expected matches. If this test fails,
we can have some more diagnostic information since we know both inputs and the
premise they are supposed to match. This is for int values.
void tap.isnt_int(int got, int expected, String test_name = 0)
This test will succeed if got and expected does not matches. If this test
fails, we can have some more diagnostic information since we know both inputs
and the premise they are not supposed to match. This is for int values.
void tap.is_float(float got, float expected, float epsilon, String test_name = 0)
This test will succeed if got and expected matches. If this test fails,
we can have some more diagnostic information since we know both inputs and the
premise they are supposed to match. This is for float values.
void tap.isnt_float(float got, float expected, float epsilon, String test_name = 0)
This test will succeed if got and expected does not matches. If this test
fails, we can have some more diagnostic information since we know both inputs
and the premise they are not supposed to match. This is for float values.
void tap.done_testing()
After you are done testing, before calling the next plan, state you are done testing.
void tap.Harness()
This outputs a small summary of currently tests and failures. Don't depend on this output format.
