Easily write and run Jasmine client and server unit and integration tests. You can use all Jasmine 2.0 features.
meteor add sanjo:jasmine
meteor add velocity:html-reporter
Tests run automatically while the app runs in development mode locally. You can see the test results in the terminal and in the html-reporter overlay.

Each testing mode has different characteristics. Each testing mode has an own folder.
- You can unit test server app code.
- The tests run isolated from your app.
- The Meteor API and all packages are stubbed in this mode.
- Place your server unit tests in the folder
tests/jasmine/server/unit/
or a subfolder of it.
Not available yet. Will be added in the near future.
- You can test client code.
- The tests are executed directly inside the browser.
- Nothing is automatically stubbed.
- Place your client unit tests in the folder
tests/jasmine/client/unit/
or a subfolder of it.
Note: Tests currently only run in Google Chrome. If you need support for another Browser please open an issue.
- You can test client code.
- The tests are executed directly inside the browser in a copy of your app.
- Nothing is automatically stubbed.
- Place your client integration tests in the folder
tests/jasmine/client/integration/
or a subfolder of it.
Tip: Use this mode when you want to test the communication between client and server. In other cases you should probably use the Client Unit Test mode.
Use the commmand:
JASMINE_SINGLE_RUN=1 meteor --test
``
### Stubs
Files in `tests/jasmine` folder (or a subfolder of it) that end with `-stubs.js` or `-stub.js` are treated as stubs and are loaded before the app code.
### Mocks
#### Mocking Meteor
This package ships with mocks for the Meteor API. You can mock the Meteor API in your tests with:
```javascript
beforeEach(function () {
MeteorStubs.install();
});
afterEach(function () {
MeteorStubs.uninstall();
});
This is done automatically for server unit tests. You need to do it yourself for your client tests if you want to write unit tests that run in the browser.
You can mock any object with the global helper function mock
.
This will avoid unwanted side effects that can affect other tests.
Here is an example how to mock the Players collection of the Leaderboard example:
beforeEach(function () {
mock(window, 'Players');
});
This will mock the Players collection for each test. The original Players collection is automatically restored after each test.
You can also create mocks manually. I would suggest to use the following pattern:
Create a mock service with a method install
and uninstall
(example for Meteor)
- install: Saves the original object and mocks it
- uninstall: Restores the original object
This pattern allows you to enable mocks only for specific tests and have a clean and independent mock for each test.
