As you may have noticed in the example above, we are rewriting the same step multiple times: Given the user is on the login page This can be exceptionally tedious, especially if we have more than one given step that is reused. Gherkin provides a solution for this by giving us another keyword to ...

type Grade is range 0 .. 15; B : Grade := 11; C : Grade := 8; Avg : Grade := (B + C) / 2; -- Avg = 9

These are the “bit fiddling” types. They have logical operators, too, such as xor, and they “wrap around” at the upper bound, to 0 again. type Bits is mod 2**24; L : Bits := 2#00001000_01010000_11001100# or 7;

A fixed point type definition specifies a delta, and a range. Together, they describe how precisely real values should be approximated as they are represented by powers of two, not using floating point hardware. Shoe_Ounce : constant := 2.54 / 64.0; type Thickness is delta Shoe_Ounce range 0.00 .....

Decimal fixed point types are typically used in accounting. They are characterised by both a delta and a number of decimal digits. Their arithmetical operations reflect the rules of accounting. type Money is delta 0.001 digits 10; Oil_Price : Money := 56.402; Loss : Money := 0.002 / 3; -- ...

If you're accepting user input for folder paths, you might need to check for trailing backslashes (\) before building a file path. The FSO.BuildPath method makes this simpler: Const sourceFilePath As String = "C:\Temp" '<-- Without trailing backslash Const targetFilePath As Strin...

If you add controls from third party libraries in a C# WPF project, the XAML file will normally have lines like this one. xmlns:xctk="http://schemas.xceed.com/wpf/xaml/toolkit" This will perhaps not work with FsXaml. The designer and the compiler accepts that line, but there will prob...

Let's assume you have a ListView wich is supposed to display every User object listed under the Users Property of the ViewModel where Properties of the User object can get updated programatically. <ListView ItemsSource="{Binding Path=Users}" > <ListView.ItemTemplate> ...

This example implements a linked list with many of the same methods as that of the built-in list object. class Node: def __init__(self, val): self.data = val self.next = None def getData(self): return self.data def getNext(self): return self.ne...

In most other languages indentation is not compulsory, but in Python (and other languages: early versions of FORTRAN, Makefiles, Whitespace (esoteric language), etc.) that is not the case, what can be confusing if you come from another language, if you were copying code from an example to your own, ...

Once using is used to introduce the name cout from the namespace std into the scope of the main function, the std::cout object can be referred to as cout alone. #include <iostream> int main() { using std::cout; cout << "Hello, world!\n"; }

If a using-declaration occurs at class scope, it is only allowed to redeclare a member of a base class. For example, using std::cout is not allowed at class scope. Often, the name redeclared is one that would otherwise be hidden. For example, in the below code, d1.foo only refers to Derived1::foo(c...

public abstract class BaseActivity extends AppCompatActivity { private Map<Integer, PermissionCallback> permissionCallbackMap = new HashMap<>(); @Override protected void onStart() { super.onStart(); ... } @Override public void setConten...

var fs = require("fs"); fs.readFileSync(‘abc.txt’,function(err,data){ //Reading File Synchronously if(!err) { console.log(data); } //else //console.log(err); }); console.log("something else"); Here, the program wa...

Sometimes you may want to have some login to determine where the user gets redirected to after submitting a form. Form Requests give a variety of ways.
