How to Fix Property does not have access type get Error in Angular Jasmine Testing

When working with Angular, you may encounter various errors during testing. One common issue developers face is the error message: "Property does not have access type get." This typically arises when you are trying to mock a getter in Jasmine tests but encounter a mismatch between the spy object and the original class. In this guide, we’ll walk through this specific error and provide a clear solution.

Understanding the Problem

Imagine you have a service that provides user information, and you've implemented a getter to access the current user’s value. As seen in the example below, you have a UserService class with a getter activeUserValue. When testing this service with Jasmine, you might want to mock this getter to return a specific user model but run into the access type error.

Typical Causes of the Error

Mismatch in Mocking Logic: Using spies effectively requires accurately configuring mock methods to simulate the original logic.

Solution: Properly Mock the Getter

To resolve this issue, you need to make sure the getter is correctly attached to your spy object. Here’s a step-by-step guide:

Step 1: Modify the Spy Object

Instead of spying on the property and trying to mock it directly, assign a value to the activeUserValue property on the spy object. This is how you do it:

Conclusion

Mocking properties in tests can be tricky, especially when dealing with getters in Angular. By properly assigning values to your spy objects, you can successfully simulate the behavior of your services without running into access type errors. If you encounter the "Property does not have access type get" message again, refer back to this guide, and you'll be on the right track to resolve the issue efficiently.
