In Salesforce it is most important to write test classes while deploying the code on Production. It helps us to do not write unused code in apex classes. While writing test classes we need to remember these testing principles.<\/p>\n
To deploy to production at-least 75% code coverage is required, but your focus should not be on the percentage of code that is covered. Instead, you should make sure that every use case of your application is covered, including positive and negative cases, as well as bulk and single records. This should lead to 75% or more of your code being covered by unit tests.<\/p>\n
1. @isTest<\/strong> must be used before starting the test class if the class version is more than 25.<\/p>\n 2. To define the test method, you can either use \u201c@isTest\u201d or \u201ctestMethod\u201d<\/strong> keyword with method.<\/p>\n 3. Stating with the salesforce API 28.0 test method cannot reside inside non test classes.<\/p>\n 4. Always use @testSetup<\/strong> method dedicated to create test records for that class. This is newly added annotation and very powerful.<\/p>\n 5. If possible Do not use seeAllData=true, Create your Own Test Data. SeeAllData=true<\/strong> will not work for API 23<\/strong> version<\/strong> earlier. User, profile, organization, AsyncApexjob, Corntrigger, Record Type, Apex Class, Apex Component, Apex Page we can access without (seeAllData=true)<\/strong>.<\/p>\n 6. Use Test.startTest()<\/strong> to reset Governor limits in Test methods.<\/p>\n 7. If you are doing any Asynchronous operation in code, then do not forget to call Test.stopTest()<\/strong> to make sure that operation is completed.<\/p>\n 8. Use System.runAs()<\/strong> method to enforce OWD and Profile related testings. This is very important from Security point of View. System.runAs()<\/strong> will not enforce user permission or field level permission.<\/p>\n 9. Use As much as Assertions like System.AssertEquals<\/strong> or System.AssertNotEquals<\/strong>.<\/p>\n 10. Always test Batch Capabilities of your code by passing 20 to 100 records.<\/p>\n 11. Always try to pass null values in every method. This is the area where most of program fails, unknowingly.<\/p>\n 12. Please use call out mock to test web-service call out.<\/p>\n 13. Maximum number of test classes run per 24 hours of period is not grater of 500 or 10 multiplication of test classes of your organization.<\/p>\n Test methods take no arguments and have the following syntax:<\/p>\n Alternatively, a test method can have this syntax:<\/p>\n Test methods must be defined in test classes, which are classes annotated with\u00a0isTest<\/strong>.
