Regular Expression (REGEX)

Regular Expression or REGEX is widely used to make searching/find characters in a string.

When you run a test on LambdaTest using a specific device, there may be scenarios, in which the particular device that you selected isn’t available. In these scenarios, REGEX will help you widen the search request for devices to run the test on.

To quote an example, consider you want to run the test on an iPhone. It doesn’t matter which one, but it’s got to be an iPhone. In these cases, we can use REGEX to specify exactly that. You’ll now be allotted any iPhone that’s available which widens the search of devices considerably.

Platform version is not mandatory only if deviceName is passed using regex. If there is no regex in deviceName, passing platformVersion is mandatory.

Usual way to pass the deviceName and platformVersion looks like this:

"device" : ["Pixel 6 Pro-12"]

Passing deviceName using REGEX:

"device" : ["Pixel.*-12"]

Right way to pass REGEX:

Pixel.*-12
Pixel.*
