Recently I was working on the Trex project: Trex testing manually a new version that we gonna release but the fact to test all the functions manually to see that works it was tedious so I decide to see the test documentation of testing in Deno.
First I thought that the unit test was easy because I had not done a test before in Deno and I say How difficult could be do a test?
a few hours passed and the same error appeared that was
AssertionError: Test case is leaking resources.
Before: {
"0": "stdin",
"1": "stdout",
"2": "stderr"
}
After: {
"0": "stdin",
"1": "stdout",
"2": "stderr",
"4": "child"
}
Make sure to close all open resource handles returned from Deno APIs before
finishing test case.
at Object.assert ($deno$/util.ts:35:11)
at Object.resourceSanitizer [as fn] ($deno$/testing.ts:78:5)
at async TestRunner.[Symbol.asyncIterator] ($deno$/testing.ts:275:11)
at async Object.runTests ($deno$/testing.ts:358:20)
there are two solutions to this:
- Close all the processes when the package was already install with .close()
- Reading the testing documentation found this to personalize the test function, by default this options comes to true the sanitizeResources, sanitizeOps
Deno.test({
name: "Install Package #1",
fn: async () =>{
await delay(1000)
const response = await installPakages(["i","--map","oak"])
assertEquals(response, { oak: "https://deno.land/x/oak/mod.ts" })
},
sanitizeResources: false,
sanitizeOps: false
});
Remember Guys read documentation :) I hope this post was helpful for u
