OpenText™ Performance Engineering for Developers

About:

An extension for executing Performance Engineering, OpenText's cutting-edge tool for web protocol performance and load testing.

Quick start:

1. Download OpenText™ Performance Engineering for Developers from OpenText MarketPlace.
2. Make sure you have created an environment variable named "DEVWEB_PATH" with the correct path to "DevWeb" folder location.
3. To create a DevWeb script, follow these steps:
   • Right-click on the editor.
   • In the options menu, select "Create DevWeb script".

Features:

1. Correlate Selection
2. Generate Javascript Code for gRPC files
3. Generate DevWeb script from HAR file

Correlate Selection

Web pages sent from the server to the browser often contain dynamic data that the client must send within later requests—for example, the session ID, which may contain a timestamp. This data changes every time you access the page.

After recording a business process, the script might contain dynamic values in the server responses. When the script is replayed, these recorded values are sent to the server. However, the web server rejects them because they are not valid in the replay session. Generally, the test fails when this happens.

Steps:

1. Open your DevWeb script.
2. Select the content you would like to correlate -> right click on it -> in the menus choose "Correlate Selection" and pick a name for your extractor:
3. An "Extractors" field was added into target step with your new extractor name and the corresponding details.
4. Now you can choose whether to replace all or specific dynamic values with the new applier that was created based on your chosen extractor name.

Generate Javascipt Code for gRPC files

gRPC (Remote Procedure Call) is a lightweight communication protocol. It facilitates service-to-service communication in distributed environments. gRPC uses protocol buffers (protobuf) as the default Interface Definition Language (IDL).

The DevWeb JavaScript SDK includes gRCP APIs that provide support for the native gRPC communication protocol. When adding these APIs to your script, you need to manually declare the methods with all the properties. This can be time consuming and cumbersome.

You can make the implementation and usage of protobuf files and gRPC methods easier, by using the DevWeb Offline Generator to convert the protobuf-format services into JavaScript functions. The generated functions can then be called from DevWeb tests. This implementation builds all the API static methods, and reduces the coding required to develop your script.

Steps:

1. Open your script that include .proto file.
2. Right click on the .proto file.
3. Select "Generate Wrapper" under DevWeb menu

Generate DevWeb script from HAR file

The basic step to generate DevWeb script from HAR file

Steps:

1. Right click on any HAR file
2. Select "Generate Script from HAR" under DevWeb menu
