These are loops in which their loop body contains no other loops (the innermost loop in case of nested). In order to have loop coverage, testers should exercise the tests given below. Test 1 :Design a test in which loop body shouldn’t execute at all (i.e. zero iterations) Test 2 :Design a test in...

A nested loop is a loop within a loop. The outer loop changes only after the inner loop is completely finished / interrupted. In this case, test cases should be designed in such a way that Start at the innermost loop. Set all the outer loops to their minimum values. Perform Simple loop testing o...

Two loops are concatenated if it’s possible to reach one after exiting the other on same path from entrance to exit. Sometimes these two loops are independent to each other. In those cases we can apply the design techniques specified as part of single loop testing. But if the iteration values in on...

The core data structure in numpy is the ndarray (short for n-dimensional array). ndarrays are homogeneous (i.e. they contain items of the same data-type) contain items of fixed sizes (given by a shape, a tuple of n positive integers that specify the sizes of each dimension) One-dimensional ar...

Associated objects are useful when you want to add functionality to existing classes which requires holding state. For example, adding a activity indicator to every UIView: Objective-C Implementation #import <objc/runtime.h> static char ActivityIndicatorKey; @implementation UIView (Ac...

if you want to iterate over numbers in reverse order? It's simple. You can use the downTo() function defined in the standard library for (i in 4 downTo 1) print(i) // prints "4321"

Is it possible to iterate over numbers with arbitrary step, not equal to 1? Sure, the step() function will help you for (i in 1..4 step 2) print(i) // prints "13" for (i in 4 downTo 1 step 2) print(i) // prints "42"

To create a range which does not include its end element, you can use the until function: for (i in 1 until 10) { // i in [1, 10), 10 is excluded println(i) }
