如何运行一个git预提交钩子来确保暂存文件的测试覆盖率不会降低？

#!/bin/bash

# 保存当前的工作目录
current_dir=$(pwd)

# 切换到项目根目录
cd "$current_dir"

# 运行测试并生成覆盖率报告
coverage run --source=./path/to/your/code -m pytest tests/

# 获取测试覆盖率结果
coverage_result=$(coverage report --fail-under=100)

# 检查测试覆盖率是否低于期望值
if [[ "$coverage_result" == *"100%"* ]]; then
    echo "Tests passed! Coverage: $coverage_result"
    exit 0
else
    echo "Tests failed! Coverage: $coverage_result"
    exit 1
fi
