An example to perform login test based on Page object pattern:
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.PageFactory;
/**
* Class which models the view of Sign-In page

.default-settings() {
padding: 4px;
margin: 4px;
font-size: 16px;
border: 1px solid gray;
}
#demo {
.default-settings;
}
The above example when compiled would only produce the following output. The .default-settings() mixin definition would not be output in the compiled CSS fi...
Android developers(mainly beginners) have been confused regarding Internal & External storage terminology. There are lot of questions on Stackoverflow regarding the same. This is mainly because of the fact that terminology according to Google/official Android documentation is quite different to...
To ensure that all possible items are documented, you can use the missing_docs link to receive warnings/errors from the compiler. To receive warnings library-wide, place this attribute in your lib.rs file:
#![warn(missing_docs)]
You can also receive errors for missing documentation with this lin...
An array is a data structure that stores values of same data type. In Python, this is the main difference between arrays and lists.
While python lists can contain values corresponding to different data types, arrays in python can only contain values corresponding to same data type. In this tutorial...
Here is an example:
my_array = array('i', [1,2,3,4,5])
c=[11,12,13]
my_array.fromlist(c)
# array('i', [1, 2, 3, 4, 5, 11, 12, 13])
So we see that the values 11,12 and 13 were added from list c to my_array.
Provided that barButtonItem has a non-null image property (e.g. set in the Interface Builder).
Objective-C
barButtonItem.image = [barButtonItem.image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
An interface is declared like a class, but without access modifiers (public, private, ...). Also, no definitions are allowed, so variables and constants can't be used.
Interfaces should always have an Unique Identifier, which can be generated by pressing Ctrl + Shift + G.
IRepository = interface
...
Classes can implement more than one interface, as opposed to inheriting from more than one class (Multiple Inheritance) which isn't possible for Delphi classes. To achieve this, the name of all interfaces must be added comma-separated behind the base class.
Of course, the implementing class must al...
Interfaces can inherit from each other, exactly like classes do, too. An implementing class thus has to implement functions of the interface and all base interfaces. This way, however, the compiler doesn't know that the implenting class also implements the base interface, it only knows of the interf...
Since the declaration of variables in interfaces isn't possible, the "fast" way of defining properites (property Value: TObject read FValue write FValue;) can't be used. Instead, the Getter and setter (each only if needed) have to be declared in the interface, too.
IInterface = interface(...
Create a file named '.jshintrc' in the root of your app, where package.json is.
*Note on windows: create a file named "jshintrc.txt". Then rename it to ".jshintrc." (notice the dot at the end).
This is a configuration file. It can for example tell jshint to ignore certain varia...
Denotes a signed integer type with "the natural size suggested by the
architecture of the execution environment", whose range includes at least -32767 to +32767, inclusive.
int x = 2;
int y = 3;
int z = x + y;
Can be combined with unsigned, short, long, and long long (q.v.) in order...
Security is a very general, broad field, and touches every aspect of development, deployment, support, among other areas. Per the (ISC)2, there are 10 domains, and include Physical security, in addition to the "Software" aspects.
The intent of information security is to protect the confid...
We can use the class DateInterval to add or subtract some interval in a DateTime object.
See the example below, where we are adding an interval of 7 days and printing a message on the screen:
$now = new DateTime();// empty argument returns the current date
$interval = new DateInterval('P7D');//th...
We can draw a connection between the Haskell types and the natural numbers. This connection can be made assigning to every type the number of inhabitants it has.
Finite union types
For finite types, it suffices to see that we can assign a natural type to every number, based in the number of constr...
A simple EntitySystem that processes a Family of entities not once per frame, but after a given interval. Entity processing logic should be placed in processEntity(Entity). For more info, please see IntervalIteratingSystem
In the below code example, the best usage for this is the physics world ...
To split strings, Guava introduces the Splitter class.
Why not use Java's splitting capabilities?
As a rule, Guava does not duplicate functionality that is readily available in Java. Why then do we need an additional Splitter class? Do the split methods in Java's String class not provide us with a...
Each signed integer type may be represented in any one of three formats; it is implementation-defined which one is used. The implementation in use for any given signed integer type at least as wide as int can be determined at runtime from the two lowest-order bits of the representation of value -1 ...
