If you need to extract information from a text response, the easiest way is to use Regular Expressions. The matching pattern is very similar to the one used in Perl. Let’s assume we want to test a flight ticket purchase workflow. The first step is to submit the purchase operation. The next step is t...

XPath can be used to navigate through elements and attributes in an XML document. It could be useful when data from the response cannot be extracted using the Regular Expression Extractor. For example, in the case of a scenario where you need to extract data from similar tags with the same attribute...

The CSS/JQuery extractor enables extracting values from a server response by using a CSS/JQuery selector syntax, which might have otherwise been difficult to write using Regular Expression. As a post-processor, this element should be executed to extract the requested nodes, text or attribute values...

JSON is a commonly used data format that is used in web based applications. The JMeter JSON Extractor provides a way to use JSON Path expressions for extracting values from JSON-based responses in JMeter. This post processor must be placed as a child of the HTTP Sampler or for any other sampler that...

When you manually write your performance scripts, you need to deal with correlation yourself. But there is another option to create your scripts - automation scripts recording. On the one hand, the manual approach helps your write structured scripts and you can add all the required extractors at the...

The SharePoint Unified Logging Service (ULS) provides support and debugging capabilities for both ops and developers. Understanding how to read the logs is an important first step to resolving issues. Tooling Microsoft provides the ULS Viewer to help read old logs and logs that are currently being...

This module implements a common interface to many different secure hash and message digest algorithms. Included are the FIPS secure hash algorithms SHA1, SHA224, SHA256, SHA384, and SHA512 (defined in FIPS 180-2) as well as RSA’s MD5 algorithm (defined in Internet RFC 1321). There is one constructo...

Returns the expression as an array. @(Get-ChildItem $env:windir\System32\ntdll.dll) Will return an array with one item @(Get-ChildItem $env:windir\System32) Will return an array with all the items in the folder (which is not a change of behavior from the inner expression.
