Annotate the method throwTrash() with and JVM will make it run once at the end of the class.Annotate the method machineReady() with and JVM will make it run once during the start of the class.We are pretty sure, that after reading the below pointers, you will get clear with lifecycle call back annotations and its workflow. The lifecycle annotations – and are the real answers to the above three questions. (For now, let us assume that we are creating this class in JUnit 4) How can we make JVM identify that the methods HotWater(), Capuccino() and ExpressoCoffee() are test cases to be run?Īnswer: The sole answer to the above questions is that the lifecycle callback annotations do all the required magic.How will we make JVM know that startMachine() and throwCup() needs to be run before running each testcase and after completion of each testcase execution, respectively?.How will we insist JVM run machineReady() only once at the class level and throwTrashandSwitchOff() at the end of the class execution?.Now, the question arises these are mere Java methods only, then: The method throwTrashandSwitchOff() runs once after all the test cases complete execution. The method machineReady() runs once while the class initiates execution. The methods machineReady() and throwTrashandSwitchOff() are class-level method which run only once for a class.
