'Unit testing with jest multiple fails but one pass?
I am just trying to do a simple test to extract a json form a collections call and I am getting weird errors that make no sense. Like all of my tests fail except one meaning it went through? Here is my test:
const base64Image = "BASE_64_IMAGE";
const imageBuffer = new Buffer(base64Image, "base64"); //1 of them passed? I am confused
var imgfile = fs.readFileSync('./tests/testImages/crystal.png', imageBuffer);
describe("POST /collections", () => {
/*
test("should respond with a 200 status code", async () => {
const response = await request(app).post("/collections").send({
myImage: imgfile
})
expect(response.statusCode).toBe(200)
})
*/
test("should Retrieve a Image", async () => { // it passed?
const response = await request(app).post("/retrievImageJson").send({
_id: "626702aa313718fb12cc11b6"
})
expect(response.headers['content-type']).toEqual(expect.stringContaining("json"))
})
})
here is the route I am testing:
router.post("/retrievImageJSON", requireLogin, async (req, res) => {
User.findOne({_id: req.user}).select("collectionArray").then( result =>{
res.send(result)
}
).catch((err) =>{
console.log(err);
})
});
and here is the test failures (there is alot weirdly)

I am just trying to make sense of this. I am not sure where it failed because some of the failures are on code that is nonexistent. If anyone has an idea on what is going on that would be super helpful.
