# Test Client - `TestClient`

You can use the `TestClient` class to test FastAPI applications without creating an actual HTTP and socket connection, just communicating directly with the FastAPI code.

Read more about it in the [FastAPI docs for Testing](https://fastapi.tiangolo.com/tutorial/testing/).

You can import it directly from `fastapi.testclient`:

```python
from fastapi.testclient import TestClient
```

	md5hex := getMD5Hash(textData)
	sha256hex := ""

	// benchmark utility which helps obtain number of allocations and bytes allocated per ops.
	b.ReportAllocs()
	// the actual benchmark for PutObject starts here. Reset the benchmark timer.

	for i := 0; b.Loop(); i++ {
		// insert the object.
		objInfo, err := obj.PutObject(b.Context(), bucket, "object"+strconv.Itoa(i),

          }
        };
    AssertionError actual = null;
    try {
      tester.test();
    } catch (AssertionError e) {
      actual = e;
    }
    assertNotNull("verify() should be able to cause test failure", actual);
    assertTrue(
        "AssertionError should have info about why test failed",
        actual.getCause().getMessage().contains(message));
  }

## 0.125.0 (2025-12-17)

### Breaking Changes

* 🔧 Drop support for Python 3.8. PR [#14563](https://github.com/fastapi/fastapi/pull/14563) by [@tiangolo](https://github.com/tiangolo).
    * This would actually not be a _breaking_ change as no code would really break. Any Python 3.8 installer would just refuse to install the latest version of FastAPI and would only install 0.124.4. Only marking it as a "breaking change" to make it visible.
