最初のSeleniumスクリプトを書く

Seleniumスクリプトを作成するための段階的な説明

Seleniumをインストールし、すると、Seleniumコードを書く準備が整います。

8つの基本コンポーネント

Seleniumが行うことはすべて、ブラウザコマンドを送信して、何かを実行したり、情報の要求を送信したりすることです。 Seleniumで行うことのほとんどは、次の基本的なコマンドの組み合わせです。

1. ドライバーインスタンスでセッションを開始します

セッションの開始の詳細については、次のドキュメントをお読みください driver sessions

        WebDriver driver = new ChromeDriver();

4. 待機戦略の確立

コードをブラウザの現在の状態と同期させることは、最大の課題の 1 つです Seleniumを使用して、それをうまく行うことは高度なトピックです。

基本的には、要素を見つける前に、その要素がページ上にあることを確認する必要がありますまた、要素は、操作を試みる前に対話可能な状態にあります。

暗黙的な待機が最善の解決策になることはめったにありませんが、ここで示すのが最も簡単なので、プレースホルダーとして使用します。

# 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.
