Testing in open source projects

-
This week in our open source class we learned about the new javascript or should I say ECMAscript.
So what is ECMAscript?
ECMAscript is a standardize javascript to foster multiple independent implementation.
It is mostly used for client-side scripting and is used in modern web technologies like node.js and react - redux frameworks.

A well way to contribute to open source project for beginners are coding testing scripts, build development and QA.

I had a look at the ECMAscript test suite experimental harness

https://github.com/bterlson/test262-harness

This test suite allows users to unit test for function in javascript.

So after setting up the environment , I ran the test using the code

test262-harness test/**/*.js


As we can see out of the 205 tests , 199 passed and 6 failed. The error shows problems with using strict mode.

After that I updated some of the test :
//Test 1
assert.sameValue(reverse, x, "value is not equal");
//Test 2
assert.sameValue(typeof reverse, typeof x, "type not equal");
//Test 3
assert.sameValue(x[2], 3, "msg for value not equal");
//test 4
assert(x[3] !== 3);

Fixing a URL bug in Brave

So this week I was working on the  Brave browser issue that was filed by our professor. The issue was based on retrieving a file path from the URL input from the user. In order to replicate the error a user has to create a file path in their local machine and try to access it using the browser URL. So I had a file named dogcat.txt located in my desktop that just contained the phrase "hello" in it. So if you try this is chrome you get the content of the file on the browser. The file displayed on chrome As you can see the URL contains the path of the file name does not need to be URL space encoded. (dog%20cat.txt) But if you try to enter the same file path on the brave URL you get a message saying the path doesn't exist. Now looking at the  source code  I saw that most of the url based code was contained in a  'urlutil.js' file that exists in 'js/lib'  subdirectory. Now there are many ways to make this issue work so I went with a very
