--test-name-pattern needing to come before filenames is hostile to npm scripts

What is the problem this feature will solve?

It is common practice to set up npm scripts for testing. E.g.

{
  "test": "node --test tests/*.js more-tests/*.js"
}

However, this cannot be combined with --test-name-pattern. Attempting to do so, e.g.

npm test -- --test-name-pattern="my pattern"

will not work, because this gets translated to

node --test tests/*.js more-tests/*.js --test-name-pattern="my pattern"

which, I believe, ends up passing --test-name-pattern="my pattern" as an argument to these test files, instead of passing it as an argument to the test runner. The correct invocation is

node --test-name-pattern="my pattern" --test tests/*.js more-tests/*.js

but this is impossible to do via npm scripts, it seems. (See alternatives considered.)

What is the feature you are proposing to solve the problem?

I don't know what a good solution to this would be. Some possible ideas:

• Special-case command line processing such that when --test is present, node grabs the --test-name-pattern argument for itself instead of passing it to scripts?

• Introduce a new binary, e.g. node_test, which processes command-line arguments in such a way? I believe this is how most test runners behave.

• Introduce a file-based customization of the test runner, including which tests to run, so that I don't have to pass the test filenames as arguments to the test runner in a way that causes this problem?

• Improve npm scripts to support a better method of passing arguments in the middle of the script? (See below.)

What alternatives have you considered?

I investigated how to get npm scripts to substitute in arguments you pass to npm run into the script command, so that the translation becomes the correct one. This is a well-studied problem, and the following two Stack Overflow posts have the best answers, as far as I can tell:

• https://stackoverflow.com/q/11580961/3191
• https://stackoverflow.com/q/37869773/3191

None of them seem very satisfactory, unfortunately. In particular, if you want something that works cross-platform, you basically have to write a wrapper script.

As an alternative, I could continue using other test runners, which support npm scripts better.

首先，使用 --test-name-pattern 复现 npm test 调用，并将其与可正常工作的命令进行比较，后者将该选项放在 --test 和文件名之前。调查 Node 对 --test 和 --test-name-pattern 的命令行处理；完成此任务需要一种明确的方案来支持这一 npm-script 使用场景，可能还需要包含参数顺序的测试。
