The key points while writing a test class are: You have to start your class with @isTest annotation, then only Salesforce will consider this class as test class. Keep your class as Private, and the best practice is to name your test class as your original Class or trigger Name + ‘Test’.

Can QA handle unit testing?
Tests can either be handled manually, where a QA team handles unit testing, integration testing, regression testing, and system testing, or automatically with tools such as Selenium, Assure Click, QTP, etc. This process is similar to other web-based applications, where testers have a clear understanding of the changes made.
Why is Salesforce history hard to test?
Code that relies on standard Salesforce history objects are hard to test, because we don't have the ability to insert history records explicitly, and inserting/updating normal records (like an Account) does not cause a history record to be generated when executing a unit test.
How to unit test a method?
The golden rule of unit testing 1 If you're not gaining coverage for a method, then you need to have a test that actually calls the method. 2 If you're not gaining coverage for an else block, then you need to have a test where you ensure that you do not satisfy the conditions to enter the corresponding if block. 3 If you're not gaining coverage for a loop, you need to make sure that your test actually has records to loop over.
What to do if you are not getting coverage for a loop?
If you're not gaining coverage for a loop, you need to make sure that your test actually has records to loop over. Most times, fixing coverage issues comes down to making sure that you create/insert appropriate test data (ideally, in a method with the @testSetup annotation).
What is the golden rule of unit testing?
The golden rule of unit testing. In unit testing, you only gain coverage for code that is executed as part of a test method. It really is that simple. You are completely in control of your unit test; so, if you're not getting coverage for part of your code, and want coverage for it, you need to ask yourself "how can I cause this code to be executed?
What is unit test?
A unit test is supposed to be just that, a test of a single "unit" of code. The definition of a "unit" of code can vary from person to person, and situation to situation, but for me it's usually a single method of the class I want to test.
Why is it good to write a test?
A nice thing about writing a variety of tests is that if you have unit tests to cover a variety of situations, you can largely stop worrying about getting enough code coverage. If you test your code against enough different situations, you will naturally gain coverage.
Why do we use unit tests?
The way I see things, the real use of unit tests is both to verify that your code behaves the way you think it should, and produces the correct output, as well as acting as a guard to alert you when changes or additions you make in the future break existing code. For both of those purposes, you need to use assertions.
What is System.AssertEquals used for?

First, It’S Important to Understand Our Prime Objectives When Testing
Test Coverage
- We often come across a situation while working on a project that requires us to pull off the test classes coverage to know the current status of our code. Testing is an important part of the Software Development Life Cycle (SDLC). Before moving the code in production, Salesforce ensures that your code has a minimum of 75% code coverage. This means ...
Recommended Process For Matching Code Coverage Numbers For Production
- Now that we understand why test coverage is important and how we can gather the data for it, let’s go through the recommended process for matching code coverage numbers for production: 1. We could use the full sandbox that is similar to the staging sandbox environment we use for production deployments. A Full Sandbox mimics the metadata and data in production and helps …
Code Coverage General Tips
- Always have a fresh pull of the code coverage, sometimes the code coverage numbers aren’t refreshed when updates are made to the Apex code in the organisation unless tests are run.
- If the organization was updated since the last test run, rerun the Apex tests to get the correct estimate of the code coverage.
- We should know that the overall test coverage of the organization doesn’t include the manag…

- If the organization was updated since the last test run, rerun the Apex tests to get the correct estimate of the code coverage.
- We should know that the overall test coverage of the organization doesn’t include the managed package tests. The exception may arise when the managed package tests cause your trigger to fire. The c...
- We know code coverage is dependent on the total number of lines of code, so if there’s any insertion or deletion of code, it would affect the code percentage. For example, let’s say an organization...

The Most Important Part of Unit Testing
- Coverage is what Salesforce requires, but code coverage alone is pretty meaningless. The way I see things, the real use of unit tests is both to verify that your code behaves the way you think it should, and produces the correct output, as well as acting as a guard to alert you when changes or additions you make in the future break existing code. For both of those purposes, you need to us…
What to Assert in Unit Tests?
- The answer here is the always helpful "it depends". You could write an assertion for almost everything under the sun, but it takes time to write assertions (and to write code that satisfies them). After a while, you'll learn what things are important to assert, and which things don't need assertions. Personally, the things I find myself writing assertions for most frequently are: 1. Initi…
You Can (and Likely Should) Have More Than One Unit Test
- A unit test is supposed to be just that, a test of a single "unit" of code. The definition of a "unit" of code can vary from person to person, and situation to situation, but for me it's usually a single method of the class I want to test. Trying to cram everything into a single unit test makes the test setup harder, and makes it more complicated to actually test things (and also harder to debug af…
