This is a draft cheat sheet. It is a work in progress and is not finished yet.
Jasmine test block
describe("A suite", function() {
describe("Optional subsection", function() {
beforeEach(function() {
// runs before every it(...) in the block
});
afterEach(function() {
// runs after every it(...) in the block
});
it("contains tests", function() {
// assert using matchers
expect(true).toBe(true);
});
});
});
|
Focused tests
|
ddescribe(block, function() { ... }) Run only tests in this block
|
|
iit(test, function() { ... }) Run only this test. Takes presedence over ddescribe(...)
|
Skipped tests
|
xdescribe( label, function(){ ... }) skip block
|
|
xit( label, function(){ ... }) skip test
|
|
|
Matchers
|
expect(1).toBe(1); match with ===
|
|
expect({a:1}).toEqual({a:1}); match simple literals and variables
|
|
expect("foo bar").toMatch(/bar/) match regular expressions
|
|
expect(foo).toBeDefined();
|
|
expect(bar).toBeUndefined(); identical to expect(bar).not.toBeDefined();
|
|
expect(null).toBeNull(); match against null
|
|
expect(1).toBeTruthy(); |
|
expect(0).toBeFalsy(); |
|
expect(["foo", "bar"]).toContain("bar"); match an item in an Array
|
|
expect(1).toBeLessThan(2); |
|
expect(2).toBeGreaterThan(1); |
|
expect(1).toBeCloseTo(1.5, 1); |
|
expect(function).toThrow(); expect( function() { throw 'error message';}).toThrow()
