junit2json-rs

junit2json-rs is a tool to convert JUnit XML format to JSON. From a library perspective, it provides a function to serialize Junit XML to Struct.

junit2json-rs is a reimplementation of ts-junit2json that is my previous work in TypeScript.

Purpose

junit2json-rs is designed for uploading test result data to BigQuery or any other DB that supports JSON.

Many languages and test frameworks support to output test result data as JUnit XML format, which is de fact standard in today. On the other hand, most DBs do not support to import XML but support JSON.

For this purpose, junit2json-rs provides a simple JUnit XML to JSON converter.

Install

shell cargo install junit2json

Usage

shell junit2json --pretry <junit_xml_file>

Output example

json { "testsuites": { "name": "gcf_junit_xml_to_bq_dummy", "time": 8.018, "tests": 12, "failures": 2, "testsuite": [ { "name": "__tests__/gen_dummy_junit/dummy1.test.js", "tests": 4, "failures": 1, "errors": 0, "time": 4.772, "skipped": 0, "timestamp": "2020-01-12T16:33:13", "testcase": [ { "name": "dummy1 Always success tests should be wait 0-2sec", "classname": "dummy1 Always success tests should be wait 0-2sec", "time": 0.414 }, { "name": "dummy1 Always success tests should be wait 1-3sec", "classname": "dummy1 Always success tests should be wait 1-3sec", "time": 1.344 }, { "name": "dummy1 Randomly fail tests should be wait 0-1sec and fail 50%", "classname": "dummy1 Randomly fail tests should be wait 0-1sec and fail 50%", "time": 0.673, "failure": { "inner": "Error: expect(received).toBeGreaterThan(expected)\n\nExpected: > 50\nReceived: 4.897277513425746\n at Object.it (/Users/kesin/github/gcf_junit_xml_to_bq/__tests__/gen_dummy_junit/dummy1.test.js:22:17)" } }, { "name": "dummy1 Randomly fail tests should be wait 1-2sec and fail 30%", "classname": "dummy1 Randomly fail tests should be wait 1-2sec and fail 30%", "time": 1.604 } ] }, { "name": "__tests__/gen_dummy_junit/dummy3.test.js", "tests": 4, "failures": 1, "errors": 0, "time": 6.372, "skipped": 0, "timestamp": "2020-01-12T16:33:13", "testcase": [ { "name": "dummy3 Always success tests should be wait 0-2sec", "classname": "dummy3 Always success tests should be wait 0-2sec", "time": 1.328 }, { "name": "dummy3 Always success tests should be wait 1-3sec", "classname": "dummy3 Always success tests should be wait 1-3sec", "time": 2.598 }, { "name": "dummy3 Randomly fail tests should be wait 0-1sec and fail 30%", "classname": "dummy3 Randomly fail tests should be wait 0-1sec and fail 30%", "time": 0.455, "failure": { "inner": "Error: expect(received).toBeGreaterThan(expected)\n\nExpected: > 30\nReceived: 12.15901879426653\n at Object.it (/Users/kesin/github/gcf_junit_xml_to_bq/__tests__/gen_dummy_junit/dummy3.test.js:22:17)" } }, { "name": "dummy3 Randomly fail tests should be wait 1-2sec and fail 20%", "classname": "dummy3 Randomly fail tests should be wait 1-2sec and fail 20%", "time": 1.228 } ] } ] } }

With jq examples

Show testsuites test count

junit2json <junit_xml_file> | jq .testsuites.tests

Show testsuite names

junit2json <junit_xml_file> | jq .testsuites.testsuite[].name

Show testcase classnames

junit2json <junit_xml_file> | jq .testsuites.testsuite[].testcase[].classname

Notice

[!IMPORTANT] junit2json-rs has some major changes from ts-junit2json. Most of the changes are to compliant with the JUnit XML Schema.

• A testsuites or testsuite key appears in the root of JSON.
• properties has property array. ts-junit2json has property array of object directly.
• skipped, error, failure are object, not array of object.
• If XML has undefined tag, it will be ignored. ts-junit2json will be converted to JSON if possible.
