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);

In this post I will talk about my experience that went into debugging , compiling and  fixing issues for the  debugger.html  project. The issue I worked on was mostly on the front- end part of the application. The issues that I worked on is listed here . First Issue Second Issue So building and compiling the project is pretty easy (at least on a mac). If you follow the following steps you can get the project up and running. My first issue got accepted and got merged in a recent commit which is always exciting.

In this post I will talk about how I went on to implement  Leaflet's  mini-map interface on a map based application called  bridge-troll . So you can check out the project  here .Its a map-based game that unlocks "troll" under bridges using open data.The mini - map library that I used in Norkart's Leaflet-MiniMap that can be found  here  . Implementing the mini - map was not easy and after my use of the library , I did notice some bugs. Firstly the websites example shows that the mini-map can be toggled using the 'ToggleDisplay' property.The example can be seen  here  . As you can see that the example can toggle the mini-map but in my example the toggle button does not show up. No toggle button This problem is already filed as an issue in the repository which can be found  here  . I did reply on this issue with example pictures. This problem really makes it hard for the mini-map to appear separated from the main map.  So I will curr
