运行Jekyll项目的构建时基本测试，您可以使用Jekyll的Liquid模板语言和脚本工具的组合。以下是如何使用Jekyll计算前置变量中的单词数的示例：
在您的Jekyll项目的根目录中创建一个名为test_word_count.rb（或其他您选择的名称）的新文件。
在这个文件中，您可以编写一个脚本，该脚本提取您想要测试的前置变量并计算单词数。以下是一个示例脚本：`require 'yaml'
从Jekyll文件中读取YAML前置内容
frontmatter = YAML.load_file('_posts/your_post.md') # 用您Jekyll文件的路径替换此处
提取您想要测试的前置变量
variable = frontmatter['your_variable'] # 用实际变量名称替换'your_variable'
计算变量中的单词数
word_count = variable.split.size
打印单词数
puts "单词数：#{word_count}"
`
将'_posts/your_post.md'替换为包含您想要测试的前置变量的Jekyll文件的路径。将'your_variable'替换为您要计算单词数的实际变量名称。
保存文件并退出。
打开您的终端或命令提示符，导航到您的Jekyll项目的根目录，并使用以下命令运行脚本：ruby test_word_count.rb
该脚本将提取前置变量，计算其中的单词数，并在终端中显示单词数。
您可以根据需要修改此示例，以适应您的特定测试需求，例如测试输出的HTML或对前置变量执行其他检查。请记得相应地更新文件路径和变量名称。
请注意，此方法假定您的系统上已安装了Ruby，因为Jekyll是使用Ruby构建的。

To run basic tests at build time for a Jekyll project, you can use a combination of Jekyll's Liquid templating language and scripting tools. Here's an example of how you can count the number of words in a frontmatter variable using Jekyll
Create a new file in your Jekyll project's root directory called test_word_count.rb (or any other name of your choice).
In this file, you can write a script that extracts the frontmatter variable you want to test and counts the number of words. Here's an example script: `require 'yaml'
Read the YAML frontmatter from the Jekyll file
frontmatter = YAML.load_file('_posts/your_post.md') # Replace with the path to your Jekyll file
Extract the frontmatter variable you want to test
variable = frontmatter['your_variable'] # Replace 'your_variable' with the actual variable name
Count the number of words in the variable
word_count = variable.split.size
Print the word count
puts "Word count: #{word_count}"
`
Replace '_posts/your_post.md' with the path to the Jekyll file that contains the frontmatter variable you want to test. Replace 'your_variable' with the actual variable name you want to count the words for.
Save the file and exit.
Open your terminal or command prompt, navigate to your Jekyll project's root directory, and run the script using the following command: ruby test_word_count.rb
The script will extract the frontmatter variable, count the number of words in it, and display the word count in the terminal.
You can modify this example to suit your specific testing needs, such as testing the output HTML or performing other checks on frontmatter variables. Remember to update the file paths and variable names accordingly.
Note that this approach assumes you have Ruby installed on your system, as Jekyll is built using Ruby.
