Using a Random Data Generator Cross-browser Testing
A random data generator can be useful if you're doing cross-browser testing. For example, if you need to write tests that fill forms with random data (such as random strings or random zip codes), then you can use this program to generate as many random data elements as you need and put them in your test cases. You can independently generate random strings of any length made out of lowercase or uppercase characters, including single-character strings. You can also generate random numbers and random text snippets from a custom alphabet. The generated data can also be used for random file names or random IDs in tests.
