All code submitted to the repository should have corresponding tests that pass. Here's how to run and write tests.
First, configure your test environment.
tests/config.tests.inc.php and set the appropriate values. You will
need a clean, empty database to run your tests. By default, name it
thinkup_tests and set the
config variable to that name. You will also need a local installation of ThinkUp; set the
config variable equal to its URL--for example,
webapp/config.inc.php, in the DEVELOPER CONFIG section, set the name of your tests database, and the username and
password to access it. This database name should match the one you just set in
In order for the tests to pass, you must:
- Have a
tests/config.tests.inc.phpfile with the correct values set
- Set the crawler log file in
webapp/config.inc.phpand make that file writable
- Set the test database name to an empty tests database which the tests will destroy each run in
- Set the test database user to a user with all privileges in the test database and global CREATE, DROP, and FILE privs
- Set caching to false in
- Have a local installation of ThinkUp using your test database
- Have a working internet connection
To run a particular test suite, like the UserDAO suite, in the ThinkUp source code root folder, use this command:
$ php tests/TestOfUserDAO.php
To run all the test suites, use:
$ php tests/all_tests.php
To run a single test, set the TEST_METHOD environment variable. For example:
$ TEST_METHOD=testIsPluginActive php tests/TestOfPluginMySQLDAO.php
The test suite assumes there is an empty tests database (like
thinkup_tests) which the default ThinkUp database user
can access. If your test needs to read and write to the ThinkUp database, extend
ThinkUpUnitTestCase and run
parent::setUp() in your
setUp() method, and
parent::tearDown() in your
tearDown() method. These methods create
an empty copy of the ThinkUp database structure to execute a test, then drop all the tables in it when the test is
complete. After you call the parent
setUp() method in your test's
setUp(), insert the data your test requires.
Best practices for writing tests are still getting developed. In the meantime, use existing tests as examples.
Model Tests (
TestOfOwnerInstanceMySQLDAO.php as an example of a set of DAO tests. Use the FixtureBuilder class to create test
data fixtures to test against.
Controller Tests (
TestOfDashboardController.php as an example of a set of controller test cases.
Plugin Tests (
All plugin-specific tests should live in the
thinkup/webapp/plugins/plugin-name/tests/ directory. Write tests
for the plugin's model and controller objects.
To test consumption of data from web services, mock up the appropriate classes and store test data to local files in
the format the API would return them in. For example, the
classes/mock.TwitterOAuth.php class reads Twitter data
from the files in the
/thinkup/webapp/plugins/twitter/tests/ for examples of Twitter crawler plugin tests.
Integration Tests (
Add tests for particular pages inside the webapp to an appropriately-named class. See
for an example.
Once your tests pass, add them to the appropriate
all_tests.php file to run with the existing suites. For example,
new model tests should go in
all_model_tests.php, new controller tests should go in
How to Debug Tests
To print variable values to the terminal while running tests, use the ThinkUpWebTestCase::debug method or ThinkUpBasicTestCase::debug method. For example, you can add a line like this to your test:
$this->debug("This is my debugging statement which will print during my test run.");
To print something other than a string in a debug statement, use the Utils::varDumpToString method, like this:
To see your debug statements, run your test like so:
TEST_DEBUG=1 php tests/yourtest.php
I'm getting lots of test failures. Help!
Possible reasons for getting a high number of test failures include:
- An incorrect $TEST_SERVER_DOMAIN in tests/config.tests.inc.php. Please make sure that this points to the web root of your ThinkUp installation. Relevant thread
- An incorrect value for any of the test database values. Please make sure that both config.inc.php and config.tests.inc.php point to an existing, empty database.
