Once your test application is ready you can connect it with code for which you want to write unit tests. Either you have you code in PCL, or in UWP app project (I assume that you applied MVVM pattern) just add reference to it in Test Application project: Now you have access to all your code from...

An artifact built by Maven can be declared as a Maven plugin by specifying the packaging as maven-plugin in the pom.xml. <packaging>maven-plugin</packaging> You need to declare a dependency on the plugin API and annotations. <dependency> <groupId>org.apache.maven&lt...

When you want for example enforce the use of the parameter Password if the parameter User is provided. (and vise versa) Function Do-Something { Param ( [Parameter(Mandatory=$true)] [String]$SomeThingToDo, [Parameter(ParameterSetName="Credentials", man...

Function Do-Something { Param ( [Parameter(Mandatory=$true)] [String]$SomeThingToDo, [Parameter(ParameterSetName="Silently", mandatory=$false)] [Switch]$Silently, [Parameter(ParameterSetName="Loudly", mandatory=$false)] ...

A synchronous producer-consumer solution ensures that the consumer reads every data item written by the producer exactly one time. Asynchronous solutions allow the consumer to sample the output of the producer. Either the consumer consumes the data faster than it is produced, or the consumer consume...

4.1 This code loads, compiles, and links a single file that creates a separate shader program for a single stage. If there are errors, it will get the info-log for those errors. The code uses some commonly-available C++11 functionality. #include <string> #include <fstream> //In C+...

Problem situation Warehouse administrator has a sheet ("Record") where every logistics movement performed by the facility is stored, he may filter as needed, although, this is very time consuming and he would like to improve the process in order to calculate inquiries faster, for example:...

Some applications may want to create so-called "Fire & Forget" tasks which can be periodically triggered and do not need to return any type of value returned upon completion of the assigned task (for example, purging old temp files, rotating logs, autosaving state). In this example, w...

3.3 Instancing can be done via modifications to how vertex attributes are provided to the vertex shader. This introduces a new way of accessing attribute arrays, allowing them to provide per-instance data that looks like a regular attribute. A single instance represents one object or group of vert...

The Iris flower data set is a widely used data set for demonstration purposes. We will load it, inspect it and slightly modify it for later use. import java.io.File; import java.net.URL; import weka.core.Instances; import weka.core.converters.ArffSaver; import weka.core.converters.CSVLoader; i...

It is often necessary to execute a long-running task and use the result of that task once it has completed. In this example, we will create two classes: One which implements the Callable<T> interface (where T is the type we wish to return), and one which contains a main() method. AsyncValueT...

In this example we will describe what happens when you scaffold a new project. First thing, the following dependencies will be added to you project (currently project.json file) : "Microsoft.Extensions.Configuration.EnvironmentVariables": "1.0.0", "Microsoft.Extensions.Co...

You can source configuration from environment variables by calling .AddEnvironmentVariables() on you ConfigurationBuilder. It will load environment variables prefixed with APPSETTING_ It will then use colon : as the key path separator. This means that : following environement settings : APPSETTI...

Character literals provide the most convenient way to express char values in Java source code. A character literal consists of: An opening single-quote (') character. A representation of a character. This representation cannot be a single-quote or a line-break character, but it can be an escap...

At the very core, your entity main DAC must have GUID column (NoteID) to reference CSAnswers table and must have field that identify the class of the Entity. We will make use of Order Type to define list of attributes to gather particular order type-specific information. Create a Graph Extension f...

While using Image/Colour as an background in a CardView, You might end up with slight white paddings (If default Card colour is white) on the edges. This occurs due to the default rounded corners in the Card View. Here is how to avoid those margins in Pre-lollipop devices. We need to use an attribu...
