Testing is an incorporated portion of the Apex, or in any software development. In Apex, we will have individual test classes for developing unit test cases. Testing is vital for successful software development. Several experts suggest that we should use a test-driven development process. The code developed should be tested instantly. So, those errors can be minimized.

If you are developing a software product for end-users, then testing is the key aspect of the success of that product. Testing is used to test the given product, whether it is working according to the expectations or not. Two methods for testing an application: one way of testing is with the help of the salesforce user interface.
Testing through the salesforce user interface makes the product testing from different perspectives. Another way of testing is testing bulk services, and you can send 200 records with the help of this code if you called through SOAP API. To implement the applications for salesforce App exchange, the following rules should be satisfied.
Observe the following:
Salesforce develops tests for the following:
1. Single Action
It is tested to check whether an individual record generates the appropriate or expected result.
2. Bulk Actions
Any Apex code like a class or a trigger or extension can be called for 1 to 200 records. You should test individual or Bulk records.
3. Positive Behaviour
It is tested to check whether the assumed behavior happens in every assumed mutation.
4. Negative Behaviour
This behavior is considered as a restriction to the applications like cannot indicate a negative amount, cannot include future data, etc.
5. Restricted user
It is used to test whether the user implements the code or gets error messages.
To ease the development of strong and flawless code, Apex endorses the execution and creation of unit tests. Unit tests are considered as class methods that test whether a specific part of code is working accurately. Methods of Unit tests will have no arguments, will not save data to the database. Unit tests should be specified in the test classes, that are written with “@isTest”.
Unit Tests Example
@isTest
Private class mindmajix {
Static void testing1() {
Program statements
}
}
Example1:
Private class Mindmajix
{
@istest static void test_1
{
Test code to be executed.
}
@istest static void test_2
{
Test code to be executed.
}
}
Apex test data is temporary and not saved in the database. After executing the test method, the inserted data is not saved in the database. All the modifications done to the available records are not saved or committed in the database. The temporary behavior of test data eases data management.
To verify the utility of the apex code, we will run the unit tests. We will run the apex test methods in the developer console.
We may run the following groupings of test cases:
We can run the unit tests through the following:

Frequently Asked Salesforce Interview Questions & Answers
Steps for Running Unit Tests are as follows:
1. In the Setup, type “Apex Test Execution” in the “Quick Find Box”, then choose Apex Test Execution.
2. Press “select Tests”.
3. Choose the tests to run. The catalogue of tests contains simply classes that comprise test methods:
4. To withdraw from gathering code coverage data while running tests, choose “Skip Code Coverage”.
5. Press Run.
In every software development, testing plays a crucial role to make it successful. In Apex also, testing is necessary to test the functionality of the product. In Apex we will check the behavior and actions of the product. We will have specific methods and classes to implement unit tests. Unit tests make the code error-free. In this way, we will test the apex code to develop a successful software product.
