Angular Unit Test Spec Builder-Angular Test Specs Setup

Example

Automatically generating the TestBed configuration for a standalone component without needing to declare it in the declarations array.

Scenario

When creating a unit test for a standalone component, developers often need guidance on how to correctly configure TestBed. The Spec Builder provides a template that includes imports, declarations, and providers necessary for the component to be tested in isolation.

Example

Creating mock classes or services to replace real dependencies in testing environments.

Scenario

In testing a service that depends on HttpClient, the Spec Builder can generate a mock HttpClient to avoid real HTTP requests, ensuring tests run quickly and reliably without external factors.

Example

Suggesting basic test cases such as component creation, input/output property checks, and interaction methods.

Scenario

For a component with input properties and event emitters, the Spec Builder suggests tests to ensure properties are correctly accepted and events are emitted under certain actions, helping developers cover fundamental behavior.

Example

Providing detailed error messages from failed tests and suggesting possible fixes or improvements.

Scenario

If a test fails because a required service was not provided, the Spec Builder analyzes the error output, identifies the missing service, and suggests adding it to the TestBed's providers array.
