The file `test_main.py` would have the tests for `main.py`, it could look like this now:

```Python
{!../../../docs_src/async_tests/test_main.py!}
```

## Run it

You can run your tests as usual via:

<div class="termy">

```console
$ pytest

---> 100%
```

</div>

## In Detail

The marker `@pytest.mark.anyio` tells pytest that this test function should be called asynchronously:

The precise details are relevant for Go implementations,
affect the specifics of error messages (such as whether
a compiler reports a type inference or other error),
and may explain why type inference fails in unusual code situations.
But by and large these rules can be ignored when writing Go code:
type inference is designed to mostly "work as expected",
and the unification rules are fine-tuned accordingly.

	Int    signed integers
	Rat    rational numbers
	Float  floating-point numbers

The zero value for an [Int], [Rat], or [Float] correspond to 0. Thus, new
values can be declared in the usual ways and denote 0 without further
initialization:

	var x Int        // &x is an *Int of value 0
	var r = &Rat{}   // r is a *Rat of value 0
	y := new(Float)  // y is a *Float of value 0

	// If no traceback function, do usual sigtramp.
	MOVQ	runtime·cgoTraceback(SB), AX
	TESTQ	AX, AX
	JZ	sigtramp

	// If no traceback support function, which means that
	// runtime/cgo was not linked in, do usual sigtramp.
	MOVQ	_cgo_callers(SB), AX
	TESTQ	AX, AX
	JZ	sigtramp

	// Figure out if we are currently in a cgo call.
	// If not, just do usual sigtramp.

// separately from Test and WithParamInterface. For example:

class BaseTest : public ::testing::Test {
  // You can inherit all the usual members for a non-parameterized test
  // fixture here.
};

class DerivedTest : public BaseTest, public ::testing::WithParamInterface<int> {
  // The usual test fixture members go here too.
};

TEST_F(BaseTest, HasFoo) {
  // This is an ordinary non-parameterized test.
