If your web application uses the SSL encryption, you need to capture HTTPS traffic instead of HTTP. To record HTTPS Traffic with JMeter, you need to configure the SSL certificates. Configure your SSL proxy Make sure the SSL proxy is configured the same way the HTTP proxy is configured: Conf...

So far we’ve covered the basic ways to record test scenarios. But one of the fastest and easiest ways to record your performance scripts, which is also free, is to use the BlazeMeter Recorder Chrome extension. These recordings can be run in JMeter or in BlazeMeter. The reason the extension is so us...

Another useful 3rd party recording tool is BadBoy. However, it works only for Windows OS. To create a new performance script: Install BadBoy here Enter the URL under test in the address bar Press the record button, shaped like a red circle and perform the actions you want to captur...

From the gnuplot 5.0 official online documentation: The command language of gnuplot is case sensitive, i.e. commands and function names written in lowercase are not the same as those written in capitals. All command names may be abbreviated as long as the abbreviation is not ambiguous. Any number...

This shows how to create the demo database used in big parts of Progress documentation: sports2000. This assumes you have installed the Progress products with at least one type of database license. Run proenv script/bat-file that will give you a prompt with all environment variables set. Create ...

Returns a new deque object initialized left-to-right (using append()) with data from iterable. If iterable is not specified, the new deque is empty. Deques are a generalization of stacks and queues (the name is pronounced “deck” and is short for “double-ended queue”). Deques support thread-safe, me...

Go supports user defined types in the form of structs and type aliases. structs are composite types, the component pieces of data that constitute the struct type are called fields. a field has a type and a name which must be unqiue. package main type User struct { ID uint64 FullName st...

because a struct is also a data type, it can be used as an anonymous field, the outer struct can directly access the fields of the embedded struct even if the struct came from a diffrent package. this behaviour provides a way to derive some or all of your implementation from another type or a set of...

the receiver of a method is usually a pointer for performance reason because we wouldn't make a copy of the instance, as it would be the case in value receiver, this is especially true if the receiver type is a struct. anoter reason to make the receiver type a pointer would be so we could modify the...

Interfaces provide a way to specify the behaviour of an object, if something can do this then it can be used here. an interface defines a set of methods, but these methods do not contain code as they are abstract or the implemntation is left to the user of the interface. unlike most Object Oriented ...

In the following example we will create a service with the name visualizer. We will specify a custom label and remap the internal port of the service from 8080 to 9090. In addition we will bind mount an external directory of the host into the service. docker service create \ --name=visual...

This simple exampe will create a hello world web service that will listen on the port 80. docker service create \ --publish 80:80 \ tutum/hello-world

import spock.lang.* class HelloWorldSpec extends Specification { @Shared message = 'Hello world!' def "The world can say hello using when and then"() { when: def newMessage = message then: newMessage == 'Hello world!' } ...

This example will show you how to use Dependency Inject to use other services registered in the Drupal environment. Imagine you have an SVG image file that changes colors depending on some random CSS/Javascript thing in your project. To be able to target the SVG with CSS you have to actually have t...

Sometimes Lua doesn't behave the way one would think after reading the documentation. Some of these cases are: Nil and Nothing aren't the same (COMMON PITFALL!) As expected, table.insert(my_table, 20) adds the value 20 to the table, and table.insert(my_table, 5, 20) adds the value 20 at the 5th po...

There are several ways to mark a comment block as a detailed description, so that this comment block is parsed by Doxygen and added as a description of the following code item to the documentation. The first and most common one are C style comments with an extra asterisk in the comment start sequenc...
