Can a before hook ever run after a test in any situation, Mocha?

My before hook runs after the initial test and at the conclusion of the second test.

Here is the code for my before hook:

before(function () {
    insightFacade.addDataset("courses", content)
        .then(function (result: InsightResponse) {
            console.log("then");
        })
        .catch(function (err: InsightResponse) {
            console.log("catch");
        });
});

It is worth mentioning that sometimes both the first and second tests fail, depending on the order in which I run them. However, the second test consistently fails.

Answer №1

Without returning the promise, Mocha is unaware that it needs to wait for it. The before hook sets up a task to execute asynchronously, allowing the first test to start in the meantime.

before(function () {
    <b>return</b> insightFacade.addDataset("courses", data)
        .then(function (result: InsightResponse) {
            console.log("then");
        })
        .catch(function (err: InsightResponse) {
            console.log("catch");
        });
});
