Writing Our First Test
Write a Cypress test in this lesson.
We'll cover the following...
Test Case with Cypress
Now that we are familiar with Cypress, we’re ready to write a test.
First, delete the cypress/integration/examples directory with all the existing Cypress tests. Then, restart Cypress with rake cypress:open. This gives us the Cypress window with a message saying that we have no tests (or, it might re-create the same sample tests, in which case just delete them again, write the next test, and then open Cypress). Let’s write the first line of a new test. Create a file named cypress/schedule/schedule_spec.js. As soon as we save it, the Cypress window changes to show that file. If we start to “Run all specs,” we get the test runner with a message that no tests are found in the file.
Now let’s start writing the test:
describe("On the schedule page", function () {beforeEach(function () {cy.request("/cypress_rails_reset_state")})it("Visits our schedule page ", function () {cy.visit("/")})})
Note: This is in JavaScript, not in TypeScript because:
a) It makes little difference when writing tests.
b) The TypeScript setup for Cypress is time-consuming.
describe vs. it Method
The test syntax here is similar to the Jasmine or Jest JavaScript tools. A describe method defines a series of tests while the it method describes an individual test. Both methods take a string argument that is a name and a function argument that is the ...
