What is difference between static methods and non static methods in Salesforce?
what is difference between static methods and non static methods in Salesforce? Static methods can be used without instantiating a new instance of the class.

How do you call private methods in test class in Salesforce?
Use the TestVisible annotation to allow test methods to access private or protected members of another class outside the test class. These members include methods, member variables, and inner classes. This annotation enables a more permissive access level for running tests only.
Can we call non-static method from Main?
We can call non-static method from static method by creating instance of class belongs to method, eg) main() method is also static method and we can call non-static method from main() method . Even private methods can be called from static methods with class instance.
Why can’t we call non-static method from static method?
You cannot call non-static methods or access non-static fields from main or any other static method, because non-static members belong to a class instance, not to the entire class.
Can we call a non-static variable in static method?
Yes, a static method can access a non-static variable. This is done by creating an object to the class and accessing the variable through the object.

How do you fix non static method Cannot be referenced from a static context?
There is one simple way of solving the non-static variable cannot be referenced from a static context error. In the above code, we have to address the non-static variable with the object name.

Methods of your test class have to be static, void and testMethod keyword has to be used.
How much coverage should Salesforce have?
Every trigger you are trying to deploy should have at least 1% coverage, but yes overall coverage of your production org after getting your code deployed should be 75%, otherwise Salesforce won’t let you deploy your code.
What does assert statement do in test?
Once your test code runs between Test.startTest () and Test.stopTest (), you must use assert statements to test whether your actual code is executing correctly and giving the results as expected. In our case, we are test whether book’s price has been set to 90 or not. If this assert statement returns false, then your test class will fail, and will let you know, that something is not correct in your code, and you need to fix your original code.

Salesforce has done that to make sure that our code doesn’t break in any situation in Production. Today we’ll see how we write the test class with example in Salesforce.
Can you test a trigger with negative use cases?
Because we are testing a simple trigger, we could not show the testing using negative use cases, but in an ideal world, you should write multiple methods in your test class, few should test your positive use cases, and other should test your negative test cases.
Is System.debug counted in Apex?
Calls to System.debug are not counted as part of Apex code coverage. Test methods and test classes are not counted as part of Apex code limit. So, no worries about writing long test class with more methods just to make sure that all your code branches are covered.
Can you deploy class code on 0% coverage?
Class can be deployed on 0% coverage as well, but as I told in last point, that overall coverage of your production org after getting your code deployed should be 75%, otherwise Salesforce won’t let you deploy your code.
