Bruno测试完成后integration-tests.sh脚本中断，无法执行清理步骤

问题现象 #

执行integration-tests.sh脚本时，Bruno测试完成后脚本直接退出，无法执行后续的"Cleaning..."及资源清理命令。

现有脚本内容 #

integration-tests.sh #

#!/bin/sh

set -e

if [ "$1" = "build" ]; then
    docker build -f ../docker/cir/Dockerfile -t registry.{url}/cir2 ..
    docker build -f ../docker/db-restorer/Dockerfile -t registry.{url}/cir-db-restorer ../docker/db-restorer
    docker build -f ../tests/scripts/Dockerfile -t registry.{url}/pester.tests ../tests/scripts
    docker build -f ../tests/bruno/Dockerfile -t registry.{url}/cir-bruno-tests ../tests/bruno

Bruno测试的Dockerfile #

FROM alpine:latest

ENV API_URI ""

RUN apk add --no-cache \
    nodejs npm

RUN npm install -g @usebruno/cli

COPY /BrunoTests/ /BrunoTests/
WORKDIR /BrunoTests
CMD ["bru", "run", "--env", "Env Cir", "--output", "result.json"]

问题原因 #

脚本开头的set -e配置会让脚本在任何命令返回非0退出码时立即终止。而Bruno的bru run命令如果有测试失败，会返回非0退出码，触发set -e机制导致脚本直接中断，跳过后续清理步骤。

解决方案 #

方案1：临时关闭set -e执行Bruno测试 #

保留set -e的同时，临时关闭该机制执行Bruno测试，记录测试结果后再恢复：

echo ""
echo "Running Bruno Tests..."

# 临时关闭set -e
set +e
docker run \
   --rm \
   --network bridge-$key \
   -e "API_URI=http://cir2/api/v1" \
   registry.{url}/cir-bruno-tests
# 记录测试退出码
BRUNO_EXIT_CODE=$?
# 恢复set -e
set -e

# 可选：根据退出码提示测试结果
if [ $BRUNO_EXIT_CODE -ne 0 ]; then
    echo "Bruno测试执行失败，退出码: $BRUNO_EXIT_CODE"
fi

方案2：强制Bruno测试命令返回0 #

在docker run命令后添加|| true，强制命令无论成功失败都返回0，避免触发set -e：

echo ""
echo "Running Bruno Tests..."

docker run \
   --rm \
   --network bridge-$key \
   -e "API_URI=http://cir2/api/v1" \
   registry.{url}/cir-bruno-tests || true

缺点：无法直接知晓Bruno测试是否真的成功，仅适合不需要关注测试结果的场景。

额外优化：确保清理步骤始终执行 #

使用trap注册退出清理函数，无论脚本正常/异常退出，都会自动执行资源清理：
在脚本set -e之后添加：

# 定义清理函数
cleanup() {
    echo ""
    echo "Cleaning..."

    docker stop cir2-$key 2>/dev/null || true
    docker rm cir2-$key 2>/dev/null || true
    docker stop mssql-$key 2>/dev/null || true
    docker rm mssql-$key 2>/dev/null || true

    sleep 5

    rm -f -r /mnt/dock-temp/mssql-$key-backups
    rm -f -r /mnt/dock-temp/mssql-$key

    docker network rm bridge-$key
}

# 注册退出信号，触发时执行清理
trap cleanup EXIT

然后删除脚本末尾原有的清理代码即可。
