How does the developer console work?

In the Developer Console, you can execute some or all tests in specific test classes, set up and run test suites, or run all tests. The Developer Console runs tests asynchronously in the background, unless your test run includes only one class and you’ve not chosen Always Run Asynchronously in the Test menu. Running tests asynchronously lets you work in other areas of the Developer Console while tests are running. Once the tests finish execution, you can inspect the test results in the Developer Console. Also, you can inspect the overall code coverage for classes covered by the tests.

How does Salesforce run Apex tests?

Before each major service upgrade, Salesforce runs all Apex tests on your behalf through a process called Apex Hammer. The Hammer process runs in the current version and next release and compares the test results. This process ensures that the behavior in your custom code hasn’t been altered as a result of service upgrades. The Hammer process picks orgs selectively and doesn’t run in all orgs. Issues found are triaged based on certain criteria. Salesforce strives to fix all issues found before each new release.

What are the benefits of Apex unit tests?

The following are the benefits of Apex unit tests. Ensuring that your Apex classes and triggers work as expected. Having a suite of regression tests that can be rerun every time classes and triggers are updated to ensure that future updates you make to your app don’t break existing functionality.

What is a test suite?

A test suite is a collection of Apex test classes that you run together. For example, create a suite of tests that you run every time you prepare for a deployment or Salesforce releases a new version. Set up a test suite in the Developer Console to define a set of test classes that you execute together regularly.

What is Salesforce code coverage?

Code coverage is a side effect of high quality unit tests. Salesforce uses code coverage as a proxy to measure the presence of unit tests in your deployments.

Can Salesforce unit tests see data?

Why is it important to write unit tests for Apex?

Write unit tests for Apex is important to make sure the code is working and produces the expected results. In this article we will learn to write unit tests methods for Apex classes, triggers, controllers, flows and processes in Salesforce.

Why should you test only one aspect of code at a time?

Should test only one aspect of code at a time to make it easier to understand the purpose. Add your test to a test suite when a new bug is found to simplify regression testing. Test-driven development or creating unit tests before writing new code can help to understand how code will be used.

Step 1. Define a private class and method

Create a new private class and define your test method inside of it. Include the @IsTest annotation on the class and method to indicate that your class will be used as a unit test.

Step 2. Create test objects and data

The Apex Toolkit exposes a number of dfsle.UserMock methods that allow you to create authorized test users that have the right permissions to execute DocuSign API methods.

Step 3. Perform the test and verify the results

The last step in defining your test method is using the Test.startTest () and Test.stopTest () methods to perform the test. Then you’ll use the System.assertNotEquals method to ensure that the results of your test were not null.

Step 4. Run the unit test

To run your test, go to the Developer console, open the Test menu, then select New Run. A table will appear that will allow you to select specific classes and tests. Select your newly created test in the left column and select Add Selected. Then select Run in the bottom right corner.

Expected output

When your unit test runs, you will see new test results data accrue on the logs tab similar to this screen. Double-click a log record to see the execution event details for that test run.
