Why do I get "Method does not exist" error if System or Test is used as class name without any namespace
|Knowledge Article Number||000126959|
If we don't use the System namespace prefix, system static class names such as Test and System can be overridden by user-defined classes with the same name I.e. if you have created a class 'Test' and reference Test.startTest(); in any class (assuming startTest() method does not exist in 'Test')..
|Resolution||As a best practice avoid using a naming convention where class names will be the same as System static classes such as Test and System.
If we have to name a class Test then ensure that any reference to system static classes are namespaced i.e. 'System.Test.startTest();'
