What is the default value of SeeAllData in Salesforce?

Hi Ankit,

It should be 'False' value by default.

Thanks.

Hi Ankit,

Its default value is false because it is not necessary to use it as it opens up data access to records in your organisation.

So Considerations for the @IsTest(SeeAllData=true) Annotation

• If a test class is defined with the @isTest(SeeAllData=true) annotation, this annotation applies to all its test methods whether the test methods are defined with the @isTest annotation or the (deprecated) testMethod keyword.
• The @isTest(SeeAllData=true) annotation is used to open up data access when applied at the class or method level. However, if the containing class has been annotated with @isTest(SeeAllData=true), annotating a method with @isTest(SeeAllData=false) is ignored for that method. In this case, that method still has access to all the data in the organization. Annotating a method with @isTest(SeeAllData=true) overrides, for that method, an @isTest(SeeAllData=false) annotation on the class.

Hope this helps you more.
