Test automation framework can have several components depending on automation planned. Some of them(though not limited to) are: Test Runner (TestNG, JUnit, Jest, Protractor, Cucumber) Test Container (BDD Specs-Steps, Junit Tests, Spec based functions) Test Environment Configuration Test Data S...

To extend and expand upon the binding experience we have converters to convert one a value of one type into another value of another type. To leverage Converters in a Databinding you first need to create a DataConverter class tht extens either IValueConverter(WPF & UWP) or IMultiVal...

iex(1)> String.contains? "elixir of life", "of" true iex(2)> String.contains? "elixir of life", ["life", "death"] true iex(3)> String.contains? "elixir of life", ["venus", "mercury"] false

To count the occurences of a value in a numpy array. This will work: >>> import numpy as np >>> a=np.array([0,3,4,3,5,4,7]) >>> print np.sum(a==3) 2 The logic is that the boolean statement produces a array where all occurences of the requested values are 1 and all o...

These function will help you to take the screenshot and also match the image with the part of the screen. .screenshot('c:\\path') #get the screenshot. .locateOnScreen('c:\\path') #search that image on screen and get the coordinates for you. locateCenterOnScreen('c:\\path') #get th...

To use multi-threading in MATLAB one can use the batch command. Note that you must have the Parallel Computing toolbox installed. For a time-consuming script, for example, for ii=1:1e8 A(ii)=sin(ii*2*pi/1e8); end to run it in batch mode one would use the following: job=batch("da&quot...

In this example, we use the default, no-args GridLayout() constructor to create a layout with a single column. public class SingleColumnGridLayoutExample { private final Display display; private final Shell shell; public SingleColumnGridLayoutExample() { display = new Di...

Similar to the Single-Column Example above, if we instead use the GridLayout(int, boolean) constructor, we can create a layout with multiple columns. In this case we create two columns, each of which are the same width. public class MultiColumnGridLayoutExample { private final Display displ...

The code example below demonstrate how you can get a lighter and darker shade of a given color, useful in applications having dynamic themes For Darker Color + (UIColor *)darkerColorForColor:(UIColor *)c { CGFloat r, g, b, a; if ([c getRed:&r green:&g blue:&b alpha:&a]) ...

In Sprite-Kit, there is the concept of collisions which refers to the SK physics engine handling how physics objects interact when they collide i.e. which ones bounce off which other ones. It also has the concept of contacts, which is the mechanism by which your program gets informed when 2 physics...

y ~ . : Here . is interpreted as all variables except y in the data frame used in fitting the model. It is equivalent to the linear combinations of predictor variables. For example y ~ var1 + var2 + var3+...+var15 y ~ . ^ 2 will give all linear (main effects) and second order interaction terms of t...
