# Тестирование { #testing }

Благодаря [Starlette](https://www.starlette.dev/testclient/), тестировать приложения **FastAPI** легко и приятно.

Тестирование основано на библиотеке [HTTPX](https://www.python-httpx.org), которая в свою очередь основана на библиотеке Requests, так что все действия знакомы и интуитивно понятны.

Используя эти инструменты, Вы можете напрямую задействовать [pytest](https://docs.pytest.org/) с **FastAPI**.

Elasticsearch uses jUnit for testing, it also uses randomness in the
tests, that can be set using a seed, the following is a cheatsheet of
options for running the tests for ES.

== Creating packages

To create a distribution without running the tests, simply run the
following:

-----------------------------
./gradlew assemble
-----------------------------

 {{{http://www.slf4j.org/manual.html#swapping}"SLF4J bindings"}}.

 Logging configuration loading is actually done by logging implementation, without any Maven extensions to support merging
 Maven installation configuration with per-user configuration for example:
 <<<$\{maven.conf}/logging>>> directory was added to core's classpath (see <<<$\{maven.home}/bin/m2.conf>>>). See your implementation

you dig right into the code, there are a few guidelines that we need
contributors to follow so that we can have a chance of keeping on top of
things.

Some of the ideas are documented in the [Maven Wiki][maven-wiki]
which might be interesting to read and for further discussion.

# 測試 { #testing }

多虧了 [Starlette](https://www.starlette.dev/testclient/)，測試 **FastAPI** 應用既簡單又好用。

它是基於 [HTTPX](https://www.python-httpx.org) 打造，而 HTTPX 的設計又參考了 Requests，所以用起來非常熟悉、直覺。

借助它，你可以直接用 [pytest](https://docs.pytest.org/) 來測試 **FastAPI**。

## 使用 `TestClient` { #using-testclient }

/// info

要使用 `TestClient`，請先安裝 [`httpx`](https://www.python-httpx.org)。

請先建立並啟用一個[虛擬環境](../virtual-environments.md)，然後安裝，例如：

```console

# 测试 { #testing }

感谢 [Starlette](https://www.starlette.dev/testclient/)，测试**FastAPI** 应用轻松又愉快。

它基于 [HTTPX](https://www.python-httpx.org)，而HTTPX又是基于Requests设计的，所以很相似且易懂。

有了它，你可以直接与**FastAPI**一起使用 [pytest](https://docs.pytest.org/)。

## 使用 `TestClient` { #using-testclient }

/// info | 信息

要使用 `TestClient`，先要安装 [`httpx`](https://www.python-httpx.org)。

确保你创建并激活一个[虚拟环境](../virtual-environments.md)，然后再安装，例如：

```console

      //   A) it's not specified that "" is the path to the working directory.
      //   B) if we're getting this path for recursive delete, it's typically not possible to
      //      delete the working dir with a relative path anyway, so it's ok to fail.
      //   C) if we're getting it for opening a new SecureDirectoryStream, there's no need to get

	// Parameters:

	// Entries to remove.
	remove := make(map[string]struct{})

	caches, _ := b.cloneCaches()

			remove[id] = struct{}{}

			logger.Info("cache ID mismatch %s != %s", id, cache.id)
