Using jsonpath expression in test?

[cyrillzadra]

Hi all ...

I'm wondering if it's possible to use JSONPath expressions within tests to extract values from a JSON response. For example, I'd like to do something like this:

test("Status test", function () {
    const jsonData = res.getBody();

    test("Response value check: customer", function () {
        const customerId = JSONPath({path: '$.customer[0].id', jsonData});
        expect(customerId .to.eql(1234);
    });

});

Thanks in advance for your help!

I was able to achieve this by installing jsonpath as an external library and whitelisting it in my Bruno configuration.

Here’s an example test script using jsonpath:

const jsonpath = require('jsonpath');

test("should return customer data", function () {
  const data = res.getBody();

  expect(data).to.eql({
    customer: [
      {
        id: 1234,
        name: "John Doe",
        email: "john.doe@example.com"
      }
    ]
  });

  const customerId = jsonpath.query(data, '$.customer[0].id')[0];
  expect(customerId).to.eql(1234);
});

And here’s my bruno.json

{
  "version": "1",
  "name": "My Collection",
  "type": "collection",
  "scripts": {
    "moduleWhitelist": ["jsonpath", "assert", "module"]
  },
  "ignore": [
    "node_modules",
    ".git"
  ]
}
