java - Powermock JUnit tests are taking more time to execute compared to normal JUnit -


We are using PowerMock by junking the static methods using annotations using @PrepareForTest . The test runs fine but the problem is that it is taking too much time to execute the test.

The code snippet is as follows: 

  @PrepareForTest ({StaticClass1.class, StaticClass2.class})

Normally However, it takes about 2 seconds to execute JUnit while joking the static method, but when we add annotation to the @PrepareForTest joke, static calls to complete the test execution It takes about a minute to take time. For a test, this is not a big effect, but we have more than 1K tests and the overall building time is taking more than 2 hours, which took 20 to 30 minutes before.

For the time being what could be the reason for the powermoke.

Any help would be greatly appreciated.

PowerMock is a tool that performs bytecode instrumentation on your generated sections. Once your classes are compiled into Java bytecode, then the powermock comes with it and modifies this generated square. It is not possible to duplicate a private or static method (using Java proxy).

You should only use the @PrepareForTest annotation in those sections that you want to use special features for PowerMock, such as joking about personal or static methods

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
