入门指南

如果你是Selenium的新手, 我们有一些资源帮助你快速入门.

Selenium 通过使用 WebDriver 支持市场上所有主流浏览器的自动化。 WebDriver 是一个 API 和协议，它定义了一个语言中立的接口，用于控制 web 浏览器的行为。 每个浏览器都有一个特定的 WebDriver 实现，称为驱动程序。 驱动程序是负责委派给浏览器的组件，并处理与 Selenium 和浏览器之间的通信。

这种分离是有意识地努力让浏览器供应商为其浏览器的实现负责的一部分。 Selenium 在可能的情况下使用这些第三方驱动程序， 但是在这些驱动程序不存在的情况下，它也提供了由项目自己维护的驱动程序。

Selenium 框架通过一个面向用户的界面将所有这些部分连接在一起， 该界面允许透明地使用不同的浏览器后端， 从而实现跨浏览器和跨平台自动化。

Selenium的设置与其他商业工具有很大不同. 在开始编写 Selenium 代码之前, 您必须安装所选语言的相关类库, 目标浏览器的驱动程序.

请点击以下链接，开始使用 Selenium WebDriver.

如果您希望从低代码/录制和播放工具开始，请查看 Selenium IDE

开始工作后，如果想扩展您的测试，请查看 Selenium Grid.

1 - 安装Selenium类库

配置自动化的浏览器.

首先，您需要为自动化项目安装 Selenium 绑定库。 库的安装过程取决于您选择使用的语言。

请求对应的程序语言

应熟练掌握build tool以安装支持java的Selenium库

其他附加思虑事项

更多的注意事项,适用于使用 Visual Studio Code (vscode) 和 C#

安装兼容的 .NET SDK 作为章节的先决条件 同时安装 vscode 的扩展 (Ctrl-Shift-X)以适配 C# 和 NuGet 可以遵照此处进行 操作指南 创建 C# 控制台项目并运行 “Hello World”. 你也可以用命令行 dotnet new NUnit 创建NUnit初阶项目. 确保文件 %appdata%\NuGet\nuget.config 已经配置完成,就像某位开发者报告的问题一样,它可能因为某种因素被自动清空. 如果 nuget.config 是空的,或者未配置的,那么 .NET 创建的Selenium项目可能失败. 加入如下章节到文件 nuget.config 如果出现清空的情况:

<configuration>
  <packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    <add key="nuget.org" value="https://www.nuget.org/api/v2/" />   
  </packageSources>
...

更多关于 nuget.config 的信息 点击. 你可能需要按照自己的需求配置 nuget.config .

现在,返回 vscode ,按下 Ctrl-Shift-P, 然后键入 “NuGet Add Package”, 并选择自己需要的 Selenium 包,例如 Selenium.WebDriver. 按下回车并选择版本. 现在你可以使用说明文档中关于 C# vscode下的案例了.

你可以查看 Selenium 对 Ruby 版本支持和最低支持. 具体位于 rubygems.org

Selenium 可以使用两种不同方法安装.

手动安装

当你完成 Selenium安装 后, 便可以开始书写Selenium脚本了.

八个基本组成部分

Selenium所做的一切, 就是发送给浏览器命令, 用以执行某些操作或为信息发送请求. 您将使用Selenium执行的大部分操作, 都是以下基本命令的组合

4. 建立等待策略

将代码与浏览器的当前状态同步 是Selenium面临的最大挑战之一, 做好它是一个高级主题.

基本上, 您希望在尝试定位元素之前, 确保该元素位于页面上, 并且在尝试与该元素交互之前, 该元素处于可交互状态.

隐式等待很少是最好的解决方案, 但在这里最容易演示, 所以我们将使用它作为占位符.

Show full example
# Running Selenium Java Tests
The following steps will guide you on how to 
run Selenium Java tests using a repository 
of `SeleniumHQ/seleniumhq.github.io` examples.

## Initial Setup

### Prerequisites

Ensure that Java Development Kit (JDK) and Maven 
are installed on your system. If they are not installed, 
you will need to download and install them. You can 
find detailed installation guides for both on their 
respective official sites.

### Clone the repository
First, we need to get the Selenium Java examples 
on your local machine. This can be done by 
cloning the `SeleniumHQ/seleniumhq.github.io` Git repository. 
Run the following command in your terminal:

```bash
git clone https://github.com/SeleniumHQ/seleniumhq.github.io.git
```
## Navigate to the java directory
After cloning the repository, navigate into the 
directory where the Selenium Java examples are 
located. Run the following command:

```bash
cd seleniumhq.github.io/examples/java
```

## Running the Tests
### Install dependencies
Before running the tests, we need to install all 
necessary dependencies. Maven, a software 
project management tool, can do this for us. 
Run the following command:

```bash
mvn test-compile
```

### Run all tests
To verify if everything is installed correctly and 
functioning properly, we should run all 
available tests. This can be done with the following command:

```bash
mvn test
```

Please be patient! If this is your first time running these tests, 
it might take a while to download and verify all necessary browser drivers.

## Execute a specific example
To run a specific Selenium Java example, use the following command:
```bash
mvn exec:java -D"exec.mainClass"="dev.selenium.getting_started.FirstScript" -D"exec.classpathScope"=test
```

Make sure to replace `dev.selenium.getting_started.FirstScript` with the path and name of the example you want to run.

# Running all tests from Selenium python example

Follow these steps to run all test example from selenium python

1. Clone this repository

```
git clone https://github.com/SeleniumHQ/seleniumhq.github.io.git
```

2. Navigate to `python` directory

```
cd seleniumhq.github.io/examples/python
```

3. Install dependencies using pip

```
pip install -r requirements.txt
```
> if you are on a different python version, for example python3.x you may have to replace `pip` with `pip3`

4. Run all tests

```
pytest
```

> Please keep some patience - If you are doing it for the first time, it will take a little while to verify and download the browser drivers

## Execute a specific example
To run a specific Selenium Python example, use the following command:
```bash
pytest path/to/test_script.py
```

Make sure to replace `path/to/test_script.py` with the path and name of the example you want to run.

接下来的步骤

大多数 Selenium 用户执行许多会话， 需要组织它们以最大限度地减少重复并维持代码更易于维护. 请继续阅读，了解如何将此代码放入您用例的上下文中 使用 Selenium.

3 - 组织和执行Selenium代码

使用IDE和Test Runner库组织Selenium的执行

如果你不仅仅只是想执行一小撮的一次性脚本，你需要能组织并编排好你的代码。 本章会启发你如何真正地使用 Selenium 代码做高效的事情。

常见用法

大部分人使用 Selenium 执行针对 Web 应用的自动化测试，但是 Selenium 其实可以支持任何场景的浏览器自动化。

重复性任务

有时候你需要往网站记录日志或者下载一些东西，或者提交一个表单， 你可以在预设的时间创建一个 Selenium 脚本去执行一个服务。

网页爬虫

你是否期望从一个不提供 API 的网站收集数据？Selenium 可以满足你， 但是请确保你了解该网站的服务条例， 因为有些网站不允许你这样做，甚至有些网站会屏蔽 Selenium。

测试

使用 Selenium 做测试需要在 Selenium 执行操作后进行断言，所以一个好的断言类库是很有必要的。 至于组织测试用例结构的一些额外特性则需要Test Runner来完成。

IDEs

不管你要用 Selenium 来做什么，没有一个好的集成开发环境，你的工作肯定不会高效。以下是一些常见的 IDE 选择：

Test Runner

即使不使用 Selenium 做测试，如果你有高级用例，使用一个 test runner 去更好地组织你的代码是很有意义的。 学会使用 before/after hooks 和分组执行或者并行执行将会非常有用。

候选

有非常多不同的 test runner 可供选择。

这个教程中所有使用到 test runner 的代码示例都可以在我们的示例目录中找到（或者正在被迁移过去）， 而且这些示例在每一次发版都会被执行，以确保代码是正确的和最新的。 下面是一份包含对应链接的 test runner 清单，其中第一项是被这个仓库和本页所有用例所使用的。

  • JUnit - 一个广泛使用的用于基于 Java 的 Selenium 测试的测试框架。
  • TestNG - 提供诸如并行测试执行和参数化测试等额外功能。
  • pytest - 由于其简单性和强大的插件，它成为许多人的首选。
  • unittest - Python 的标准测试库
  • NUnit - .NET的流行单元测试框架
  • MS Test - 微软自己的单元测试框架
  • RSpec - Ruby中运行Selenium测试最广泛使用的测试库
  • Minitest - 一个随Ruby标准库附带的轻量级测试框架
  • Jest - 主要作为React的测试框架而闻名，但也可以用于Selenium测试
  • Mocha -最常用的运行Selenium测试的JavaScript库。
  • Kotest - 一个灵活且全面的测试框架，专为 Kotlin 设计。
  • JUnit5 - 标准的 Java 测试框架，完全兼容 Kotlin。

安装

在安装 Selenium 类库一节中详细说明了需要哪些东西。 这里的代码只展示在我们的文档示例项目中用到的示例。

Maven

Gradle

To use it in a project, add it to the requirements.txt file:

in the project’s csproj file, specify the dependency as a PackageReference in ItemGroup:

Add to project’s gemfile

In your project’s package.json, add requirement to dependencies:

# Running all tests from Selenium python example

Follow these steps to run all test example from selenium python

1. Clone this repository

```
git clone https://github.com/SeleniumHQ/seleniumhq.github.io.git
```

2. Navigate to `python` directory

```
cd seleniumhq.github.io/examples/python
```

3. Install dependencies using pip

```
pip install -r requirements.txt
```
> if you are on a different python version, for example python3.x you may have to replace `pip` with `pip3`

4. Run all tests

```
pytest
```

> Please keep some patience - If you are doing it for the first time, it will take a little while to verify and download the browser drivers

## Execute a specific example
To run a specific Selenium Python example, use the following command:
```bash
pytest path/to/test_script.py
```

Make sure to replace `path/to/test_script.py` with the path and name of the example you want to run.
