How to Store Session Throughout All Tests in Cypress

When working with Cypress for end-to-end testing, one common issue that developers encounter is the loss of session data between tests. This frequently translates into problems where user sessions—like login states and cookies—get cleared after each test or it() block. If you're a beginner exploring Cypress 10 or are looking for a solution to this issue, you're in the right place!

In this guide, we'll dive deep into how to manage user sessions effectively, ensuring that your tests retain the necessary session throughout their execution.

The Problem: Session Lost Between Tests

As you run tests in Cypress, it can be frustrating to see that every test resets the session state, requiring needless repeat logins or setups. This not only complicates test writing but also affects performance due to redundant calls to establish sessions.

Here's a portion of the code that illustrates the problem:

The code above shows clearly that after running the before() method, the session clears for every it() block you execute. This can lead to unwanted behaviors like not being logged in, which is inconvenient while testing.

The Solution: Using cy.session()

The good news is that Cypress provides a method called cy.session() to help manage session data across multiple tests without re-authentications. Below is how you can implement it effectively:

Step 1: Implement beforeEach() with cy.session()

To keep your session alive throughout tests, you'll want to replace the cy.visit() calls in each it() block with cy.session(). Here’s how to restructure your code:

By doing this, cy.session() will maintain the session for each test and will only call prepare() the first time it's invoked. This way, all cookies created remain in cache for subsequent tests.

Step 2: Persistent Location Management

To preserve the last visited location between it() calls, implement an afterEach() function to capture the current location after each test execution:

Now, on your next beforeEach() execution, simply perform a cy.visit(location) call to return to the last visited site.

Step 3: Example Implementation

Bringing it all together, your test suite implementation should look something like this:

Conclusion

By adopting cy.session() along with smart session management strategies like beforeEach() and afterEach(), you can maintain user sessions throughout your Cypress tests effectively. This not only saves time but makes your tests more robust and reliable.

Now that you're equipped with this knowledge, go ahead and improve your testing workflow with seamless session handling in Cypress!
