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...

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...

In Go a method is a function that acts on a variable of a certain type, called the receiver the receiver can be anything, not only structs but even a function, alias types for built in types such as int, string, bool can have a method, an exception to this rule is that interfaces(discussed lat...

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...
