Bazel sh_test 找不到节点

Question

我正在尝试运行需要 node 的脚本。我的机器上安装了节点。我可以通过 bazel run //:sh_bin 运行 sh_binary 和脚本运行s 节点就好了：

sh_binary(
    name = "sh_bin",
    data = [
    ],
    srcs = [":script.sh"],
)

script.sh:

node -v

bazel run //:sh_bin:

v14.17.6

现在我想将其转换为 sh_test:

sh_test(
    name = "sh_bin",
    data = [
    ],
    srcs = [":script.sh"],
)

但现在bazel test //:sh_bin找不到节点：

node: command not found

我也尝试将 local = True 添加到测试中，但仍然是同样的问题。

Answer 1

Bazel 测试运行在比应用程序运行通过 bazel run 更受控制的环境中。 测试运行ner 建立的初始条件之一是 $PATH 的值：https://docs.bazel.build/versions/main/test-encyclopedia.html#initial-conditions

如果您正在使用远程执行，另一个问题可能是您的测试是在没有安装节点的机器上执行的。

努力实现独立于主机状态的运行和测试的密封构建始终是一个好主意。这意味着您需要使 node 程序可用于您的二进制文件或作为 data dep.

进行测试

一个很好的选择是建立在现有工作的基础上，例如 https://github.com/bazelbuild/rules_nodejs。

话虽这么说，你的例子对我来说确实有效。

cd `mktemp -d`
touch WORKSPACE
echo "node -v" > script.sh
chmod +x script.sh
cat <<EOF > BUILD
sh_test(
    name = "sh_bin",
    srcs = [":script.sh"],
)
EOF
bazel test --test_output=all -- //:sh_bin
