Mutation testing with PIT

developer-help — Mon, 19 Apr 2021 11:45:04 +0000

Ever wondered what metric can be used to measure quality of Unit test. Mutation testing comes to the rescue. This video will use PIT library to enable Mutation testing in Junit tests. It explores how to read the test report generated. It also gives some of the pitfalls that one has to avoid when enabling mutation testing.
In below video, i shared step by step guide to enable Unit test quality metric using PIT. It also discusses some of the future work areas one can try.

Sikuli Based Image Automation

developer-help — Tue, 30 Mar 2021 07:48:24 +0000

Sometimes Salenium is not the answer to your automation needs, we need to rely on image based automation. Thus Sikuli gives you easy way of doing automation based on image. Uipath is also competing in same area with a cost associated with it.

I created below Tutorial to give how easy it is to create automation base.

Basic auth deprecation on github and its impact

developer-help — Tue, 05 Jan 2021 09:12:11 +0000

Basic auth deprecation on github and its impact.

Till now Github was supporting basic Authentication for making an API call for git.
But starting nov-20 git stopped supporting basic Authentication as mechanism for authentication.

As per git alternative is to use personal token for authentication for GIT API calls.

Though personal token is there from long time but there is no clear cut details about
what exactly works that is how i scrambled over net to figure out what works.

Below set of details with curl, that works and does not work.

curl -H "Authorization: Bearer " -H "Accept: application/vnd.github.v3+json" https://api.github.com/repos/developer-help/Test-Token/contents/pipeline.json

Does not work
curl -H "Authorization: Token " -H "Accept: application/vnd.github.v3+json" https://api.github.com/repos/developer-help/Test-Token/contents/pipeline.json

Does not work
curl -H "Authorization: Basic " -H "Accept: application/vnd.github.v3+json" https://api.github.com/repos/developer-help/Test-Token/contents/pipeline.json

Android Tips for new bee in 2020

developer-help — Mon, 20 Jul 2020 07:02:05 +0000

Hi All,

I compiled my thoughts for new bees to android. There is lot on net that one has to unclutter before he/she can make sense for Android App development. I tried capturing the must knows and keep the focus so one should not feel lost. As android is under development from last many years. People tend make assumptions thus giving nightmares to new bees.
Below is the link for the video.

Curious case of Git delete with jenkins pipeline

developer-help — Thu, 02 Jul 2020 10:30:30 +0000

Hi Guys,

Today i want to share a unique use case of delete remote git branch command with jenkins pipeline. All a job is doing some work checkin to a branch, merge it with master and want to delete once everything is done.

It is simply captured with below set of command from commandline

git checkout branch
git commit
git push

git checkout master
git merge branch
git push
git branch -d branch//local branch delete
git push origin --delete branch

This is simple if you are doing it from the your dev machine, but not so with jenkins pipepline running in cloud with some cloud provider.

One of the key things to note hear is, git is not secured protocol and you can't directly communicate on top of it, because cloud providers rule will whitelist the delete command, because it can see the content.

So we have to use https to communicate with remote git repo.

I modified the command like this

withCredentials([[
$class: 'UsernamePasswordMultiBinding',
credentialsId: 'my-git-credential-id',
usernameVariable: 'GIT_USERNAME',
passwordVariable: 'GIT_PASSWORD'
]]) {
sh 'git push origin --delete branch'
}

considering this will go through, but this command keeps on hanging without any clues.

Now the second attempt was to change it like this circumventing whitelisting of the cloud provider.

But still it is not working, with all the thoughts being put through of why it is not working.

Than finally comes Eureka moment where i just interchanged order of commands, as with https url in git command flags are the last one to end the command with argument preceding them.

Why not to create db asset from code

developer-help — Wed, 01 Jul 2020 10:09:42 +0000

Hi All,

I read many articles related to self provisioning system where application is capable of creting db assets on first deployment. I have slightly different views on this. Below are the reasons.

Difficult to make changes without redeploying the code as there is tight coupling between code and assets needs to be created or modified.
Permissions needs to be given to the system/super admin user that is running the application.
As a repercussion of two if security of your deployed application is compromised than you may loose your DB.
Most of the financial org. avoids this due to security aspects.

Overall, do read out on new options that are getting traction but do diligence on new features if it makes sense in the context that you are applying them.

Fallacies of Async programming

developer-help — Sun, 23 Feb 2020 07:36:14 +0000

Hi Guys,

I want to share another fallacy of async programming where developers often think it is a synchronous program. This situation just happened when I was doing pair programming with one of the team members. There was a an existing code this person has already written and we were debugging why it is not save as well as not throwing exception. In order to make it more clear.

Consider below code snippet which looks simple, ignoring the syntax and just showing async nature stuff.

public class BasicCrudOperations
caller() {
calledMethod(arg1, arg2, arg3);
}

private calledMethod(String a, String b, String c) {
System.out.println("This is my work");
try {
()-> { MongoDB.save(a,b,c);
}

}
} catch(Exception e) {
e.printStackTrace();
}

In the above code caller is calling called method in sync fashion and doing try catch around async lambda expressions. Now developer expects that if something fails exception will occur and being caught in catch block. Essentially this will never happen as call to Mongo save operation happens in separate thread nothing to do with current thread calling calledMethod from caller. This trap will not be visible until we go to production/preprod/testing environment where things go still developer wonder why i am not seeing exception. Make sure you handle such scenarios proactive during reviews.
Happy Coding.
