Screen the embedded array depending on the criteria

Here is an example of an object I have:

data = 
    {
        "suites": [
            {
                "status": "fail",
                "testcases": [
                    {
                        "status": "pass"
                    },
                    {
                        "status": "fail"
                    }
                ]
            },
            {
                "status": "pass",
                "testcases": [
                    {
                        "status": "pass"
                    }
                ]
            }
        ]
    }

I am trying to determine the count of test cases that have passed and failed (In this case pass: 2, fail: 1). I attempted the following code to get the pass count:

data.suites.filter(suite => {
    suite.testcases.filter(testcase => {
        return testcase.status === 'pass';
    })
}).length

Unfortunately, the result is not what I expected.

An effective way to keep track of occurrences is by utilizing an object for counting purposes.

var occurrences = { "categories": [{ "type": "apple", "quantity": 5 }, { "type": "orange", "quantity": 3 }] },
count = {}

occurrences.categories.forEach(category => 
    count[category.type] = (count[category.type] || 0) + category.quantity);

console.log(count);

Give this a shot:

let testResults = {"runs": [{"outcome": "failed","tests": [{"outcome": "passed"},{"outcome": "failed"}]},{"outcome": "passed","tests": [{"outcome": "passed"}]}]};
const outcomes = testResults.runs.reduce((a, b)=> a.tests.concat(b.tests)).map(x=> x.outcome);
console.log(outcomes.filter(x=> x === "passed").length) // 2
console.log(outcomes.filter(x=> x === "failed").length) // 1

To effectively count the number of pass and fail occurrences, you can utilize the Array#reduce method and store the results in an object like this: {pass: 2, fail: 1}

var testRuns = {"suites": [{"status": "fail","testcases": [{"status": "pass"},{"status": "fail"}]},{"status": "pass","testcases": [{"status": "pass"}]}]};

var results = testRuns.suites.reduce( (accumulator, current)=> {
  current.testcases.forEach(testCase=>{
    testCase.status === 'pass' ? accumulator.pass++ : accumulator.fail++;
  });
  return accumulator;
}, {pass: 0, fail: 0});

console.log(results);
