@usualoma @yusukebe extra tests for not found error with compress middleware

Thanks for creating the PR.

I like the idea of more testing, but on the other hand I think it is also true that more test code is also more maintenance cost. I believe we need a test code for our needs.

I think the file src/middleware/compress/index.test.ts should contain tests related to the middleware of compress. The “matched route that includes only one middleware breaks applying order “ (#2080) is a bug of hono's own, not of the middleware.
Also, the middleware of compress does not contain any code related to 404.

Given that, I see no need for this PR test code in src/middleware/compress/index.test.ts.

Do you think that "in the future, regressions that cannot be detected by the test code of hono itself can be detected by this test code?"

@usualoma i agree with you more tests is more maintenance, so lets keep it as you mentioned, but please check honojs/node-server#130
