How to write a simple test class in salesforce

The way to best achieve this is to write a static page reference comparison method. Test methods and test classes are not counted as part of Apex code limit. Parameters and other variables can also be added to the page references.

See the following example. Because we are testing a simple trigger, we could not show the testing using negative use cases, but in an ideal world, you should write multiple methods in your test class, few should test your positive use cases, and other should test your negative test cases.

Good luck with your test classes!! Not really the most helpful message in the world, as the two are seemingly identical: This will iterate through the different page reference attributes and compare them one by one.

If this assert statement returns false, then your test class will fail, and will let you know, that something is not correct in your code, and you need to fix your original code. It sounds simple enough, but testing these page references is not as straightforward as you might think.

Write Salesforce Text Class for Apex Trigger

When writing tests for Apex controller classes, it is likely that you will have to write test methods that relate to action methods.

In the example below, we will learn how to write a very simple test class: The simplest way to avoid this problem is to simply compare the URL attributes of the page references, like so: But this should not be our focus. Take the following example of a simple controller method and an accompanying test method.

These methods help you to reset your governor limits just before your actual code of testing get executed. Methods of your test class have to be static, void and testMethod keyword has to be used. So, no worries about writing long test class with more methods just to make sure that all your code branches are covered.

Writing unit tests for the PageReference Class Before you can deploy any Salesforce project to production, unit tests have to be written that ensure that future releases or platform upgrades do not cause any element of your system to malfunction.

Action methods in controllers have to return a Page Reference, which can be used to direct the user to another page as soon as the action completes. This will allow you to easily compare two page references quickly and effectively. To achieve a suitable level of coverage and fault tolerance, your test methods should ensure that calling an action returns the correct page reference.

Prepare your test data which needs to be existing before your actual test runs. There are multiple techniques of creating test data now a days, for example, setup method, static resources etc. You have to start your class with isTest annotation, then only Salesforce will consider this class as test class.

Will cover in more details in other article. Some points regarding the test classes in Salesforce, which you have to know for sure:All the test code does is create a new user using Apex, thereby triggering the execution of our simple trigger.

Let’s start with the outer layers. All this code does is tell Salesforce we are writing test code. Testing Example. The following example includes cases for the following types of tests: Testing with other users; The test is used with a simple mileage tracking application.

The existing code for the application verifies that not more than miles are entered in a single day. Here is the entire test class.
