Test Structure

Tests can be grouped logically inside a describe() block.
describe("a set of tests", () => {
  // put some tests in here
});
Some tests can be nested in groups like this.
describe("a set of tests", () => {
  // a nested group
  describe("a nesting of tests", () => {
     // put some tests in here
  });
});
Now, as-pect will logically group the nested tests within the top level group and the nested group.
The following top level functions are provided to you as units for test grouping.
/**
 * Common practice for using the test() function is to name
 * the test after the thing that is being tested.
 */
test("some noun or verb", () => {});
​
/**
 * Common practice for using the it() function is to name it
 * after a tested behavior.
 */
it("should do something as expected", () => {});
​
/**
 * For tests that are incomplete and need review, or shouldn't
 * run because they describe behavior that is not supported yet,
 * use the xit() and xtest() function to have the module ignore
 * that test.
 */
xtest("something that shouldn't run", () => {});
xit("shouldn't run", () => {});
​
/**
 * In jest, you can check to see if a function throws an error
 * by using the expect(func).toThrow() expectation. However, this
 * can become tedious to write, and as-pect has a few functions
 * that allow you to describe unreachable behavior with less code.
 * Use the throws() and xthrows() function to describe a test that
 * is expected to fail.
 *
 * Name your test after the condition that causes your test to error.
 */
throws("when it should throw", () => {});
itThrows("when it should throw", () => {});
​
/**
 * For setup code that runs ONE time before a group is tested,
 * use the beforeAll and afterAll function to run code once per group.
 */
beforeAll(() => {});
afterAll(() => {});
 
/**
 * For setup code that runs every time before each test is tested,
 * use the beforeEach and afterEach function to run code once per test.
 */
beforeEach(() => {});
afterEach(() => {});
Jest supports nested tests, but this feature is currently unsupported by as-pect. However, this will be supported when 4.0.0 is released.
