Before we can begin writing Cypress tests, we first need to install it. Within your terminal type the following: Now that we have Cypress installed, we can launch it with: With the Cypress 10 and later, we are now presented with the ability to write E2E or component tests. In this course, we are going to focus solely on E2E tests. Components tests ...
Open the cypress/e2e/home.cy.tsfile in VSCode. This is the default test that Cypress created when we asked it to create our spec file. We need to update it to run tests against our course application, but before we do that, let's break down the code that is in this file. On the first line, we see what is commonly referred to as a “describe block.” ...
Cypress is throwing an error and says that it cannot load localhost:3000. The reason this is happening is that our applications dev server is not running. When running our Cypress tests we always need to have our application running, otherwise, we are going to see this error. Since Cypress is currently running in our terminal like so: We need to op...
Now that we understand the basic makeup of a spec file and a test, let's write our test that verifies the h1on the home page contains the correct text. The first thing we need to do is tell Cypress which element to get, which in this case is the h1 Typically a page should only have a single h1 if they are following SEO best practices, which is true...
Let's briefly discuss what is happening on this line: First, we are using cy.get() to get the h1element on our home page. Next, we are chaining another command called contains onto the cy.get() which accepts a string. We are passing into the contains command a string of text which we expect to be inside of the h1element. Command chaining is when yo...
While we are just getting started with writing Cypress tests, we think it is important to help you understand some best practices along the way. In our first test we are getting the h1element by simply passing in the element to cypress, like so: While this obviously works, because our test is passing, this is not ideal. Why? If you take a look at t...
Now that you have learned about using dataspecific test attributes on elements, let's now update our test to see how this works in practice. Currently our test looks like this: We are going to replace the cy.get("h1") with the data-testattribute. If we open up Chrome’s dev tools and inspect the heading we will see it has the following HTML markup. ...
Next, we are going to write one more test in this lesson that verifies the features in the hero of our homepage are correct. If we use dev tools to inspect one of these features, we will see the following HTML markup. There doesn’t seem to be any data-test attributes or anything very specific we can use within cy.get() to get these elements. While ...
Now that we have two tests, each time we save our file, Cypress is going to re-run all of the tests in this file. This is ok when you only have a few tests, but what if we had dozens of tests in this single spec file? Each time we saved we would have to wait until Cypress finished running all of our tests. This is not ideal especially when we are r...
We still need to write two additional assertions for the remaining two features, which we are going to ask you to write for practice. Pay close attention to this line You can copy and paste this line with minor tweaks to test for the other features. You will need to reference the correct index in the array and update the text the feature contains. ...
