Example text

When you include calls to external services in your service's constructor method, you make it very hard to test and debug. If the external service call fails during your service's initialization, the call might throw an exception, causing your service to not be created. Not only can this cause your entire application to not start up, but it could cause your application to fail later on when the service is instantiated for the first time. I like to create an init method for my services that need to retrieve external data; this way, I can initialize the service in a module's run method, which executes after the application starts up and before the first view is displayed.

In the following code, we've defined the same logging service, but using a provider method. We've moved the init method out of the service's definition to the provider's definition and created two other methods to allow the consumer to set the log level for the service and add a logging appender to the service, making the service more configurable overall. fatal(message); } return { trace: trace, debug: debug, info: info, warn: warn, error: error, fatal: fatal }; } }; return logging; }); })(); To review, use the constant method if you need to define values that will not change over the course of your application.

Not only can you replace the behavior of a service method, but you can also check to see if a service method was called, how many times it was called, and with what arguments it was called. Another good thing about spies is that they only exist inside the describe or it functions where they were defined, allowing you to provide different behavior for the same method in each different unit test if needed. In the following unit test, we have defined a spy for the trace method of the log_service using the spyOn method, and passing in the instance of the service and the name of the method to watch.
