Testing using Jasmine

• Jasmine and karma are used for executing tests.
• Tests are written in a file named as <>.spec.ts. Example login-component.ts will have login-component.spec.ts.
• describe and it are the functions used to write a test case
  • describe used for defining test-suite.
  • it for defining a spec or a test

describe('<<TestSuite Name>>',() => {
    it('<<Test Name>>', () => {
        const result = <<method-name-inputs>>;
        expect(result).toBe(<<Expected-Result>>);
    })
})
//if it works test will be successful else the test will fail

Provide proper names for test suite and the test names so you know what you are testing next time.

• To execute test you have to run ng test
• General rule for testing is arrange asset and act.

Writing test script for a component

• import the component and check for the component values once the test is done
