Regex Random String Generation Support

In addition to a simple way to generate random data, testRigor also supports a way to use Regular Expressions (Regex) for more complex scenarios. For instance, you can generate a random tag like this:

generate by regex "<(a|button)>data<\/\1>", then enter into "Tag data" and save as "generatedTag"

which generates <a>data</a> or <button>data</button>. Or you might want

generate by regex "https://(www\.)?([a-z][a-z0-9-]{2,30}[a-z0-9]\.){1,5}(com|edu|co\.uk|info|io)", then enter into "URL" and save as "generatedUrl"

which generates a unique URL in the format of “https://www.abc.de.com”.

The rule of thumb to use ReGex is to avoid it as much as possible since it is very hard to read for anyone who is not familiar with it. Always try simple template first. One of the use cases where you might be forced to use ReGex is if what you generate must have a variable length.

testRigor supports both generation of random strings based on Regex as well as validating and extracting data.

Regex Random Data Generation Cookbook

For simple scenarios like generating emails, phone numbers, credit card numbers, etc. please see simple template. The full command will look like this:

generate by regex "", then enter into "Email" and save as "newEmail"

Regex Random Generation Syntax Support

testRigor provides full support for Java-like regular expressions with POSIX character classes and full multibyte Unicode support for international characters. A simple example is:

generate by regex "[A-Z][a-z]{2,50}", then enter into "Name" and save as "generatedName"

Advanced Topics

When we were creating the Regex generator we wanted the syntax to be as close as it is technically possible to Java version of Regex (Pattern). You might find a lot of additional quirks and features to be similar to Java’s version. However, the parser was built from scratch and had to be generation-compatible, so there are some differences. For instance, we included support for almost all POSIX character classes. However, we emulated how Java works with backreferences and group numbering. Also, we tried to build parser in a way that would produce the most readable and understandable error messages we could do.

More simple use cases like phone numbers, passport numbers, SSNs, emails, etc. see simple template.

Regex for validations and search

You can use Regex for search/validation in testRigor. testRigor will use Java 11's Regex Pattern to complile/process the Regex in this case. See the full supported syntax here. Examples of usages are:

check that page has regex "Current time: [0-2][0-9]:[0-5][0-9]"
check that page doesn't have regex "fail|crash|500"
check that URL matches regex "https://mycompany\.com/list/item/[a-z0-9]{2,30}"
check that text below "Current time" matches regex "[0-2][0-9]:[0-5][0-9]"
grab value of regex "[0-2][0-9]:[0-5][0-9]" and save it as "currentTime"
