Force timeout for testing? about regexp2 HOT 3 CLOSED

There's no way to force this via the library directly. The regex in your example doesn't have any backtracking so there's basically no chance of a timeout unless you give it an enormous amount of input. And even the engine can process gigabytes per second. I'd recommend just not setting a MatchTimeout in this case.

If you really want to have a timeout and test it like this then In your example I'd make the StringMatches function modal so you can set it up to sometimes return an error for testing purposes.

Then there is no way to achieve 100% coverage of code that uses this library in such a situation. Basically, there should be a MatchString that does not return a timeout error at all.

If you don't set a timeout then you can ignore the err param since it'll never be set: result, _ = regex.MatchString(input) and you'll be all set.
