`oglematchers` is a package for the Go programming language containing a set of
matchers, useful in a testing or mocking framework, inspired by and mostly
compatible with [Google Test][googletest] for C++ and
[Google JS Test][google-js-test]. The package is used by the
[ogletest][ogletest] testing framework and [oglemock][oglemock] mocking
framework, which may be more directly useful to you, but can be generically used
elsewhere as well.
A "matcher" is simply an object with a `Matches` method defining a set of golang
values matched by the matcher, and a `Description` method describing that set.
For example, here are some matchers:
```go
// Numbers
Equals(17.13)
LessThan(19)
// Strings
Equals("taco")
HasSubstr("burrito")
MatchesRegex("t.*o")
// Combining matchers
AnyOf(LessThan(17), GreaterThan(19))
```
There are lots more; see [here][reference] for a reference. You can also add
your own simply by implementing the `oglematchers.Matcher` interface.
