Regression testing




When you are working on a project, generally test cases become thousands in number within a very few releases.

How do you manage those and how will you decide which ones to repeat in your next releases?

Assume you developed 3 modules newly. Each module is having 50 test cases which you ran in the sprints of development of feature functionality testing cycles

Here are some of the hints to decide upon the reuse ability of the test cases.

Do's:

  • Test those modules which use the same code as the newly developed modules
  • Choose the test cases of basic operations on the modules
  • Use tagging to tag same test cases for feature functionality testing as well as regression testing
  • Choose all the corner cases of testing
  • Test for special type of data
  • Test those cases which were broken in the earlier testing cycles
  • Test with different types of user logins(Customer, Admin, Super Admin)
  • Test functionalities that send emails
  • Test functionalities that are run through cronjobs


Dont's:

  • Browser testing each module
  • UI testing
  • Testing the loading of a pop up or a window. Include testing any operation on this pop up or window which imperatively tests the loading of pop up
  • Modules whose code was not meddled with(Sanity testing these modules is a must though)

With addition of 150 new test cases to your test cases base, it will be good to choose 20% of it as Regression test cases and 10% of it as Sanity test cases.

Bug bounty - Simple tips and tricks

Image
Its been a couple of months that I am bug hunting and I think I got hang of it now. Bug bounties are the most fancied way of earning money among the ethical hackers and otherwise engineers. I get many requests on Linkedin and Telegram to teach them about bug bounty. I have followed a few big time bug hunters and learnt from them. There are awesome writeups, podcasts and tutorials on Pentester.Land Here are a few tips and tricks to get started with any bounty program. Follow platforms like HackerOne and BugCrowd. They have organised bounty programs which reward in points and money according to the priority of the bug found. They have charity programs too if you wish to donate. So, when there are new programs launched for websites, mobile apps and APIs, you get to see whats in scope of the program and whats not. If you are reporting a bug thats not in scope, you get -ve points. There will be rules of the program which you MUST read carefully to understand the type of progra...

Hashing, Salting, Encoding and Encrypting

Image
One of the most asked questions when you say you are a cybersecurity engineer is that whats the difference between hashing, encoding and encryption. Many great blogs are available out there to answer that question. I try to make things simple so a layman gets it right. Hashing Hashing is a one way function where the given string is converted to fit in to a fixed length string using hashing algorithms. Simply put its a set of rules that convert the text in to a fixed length text. Hashing is basically used to check the authenticity of data. Assume you have a file that should be downloaded from a website. First you hash the file and digitally sign it. Now you hash the signed file too and encrypt(will talk about this later). The browser that downloads the file at the client end will get these two hash values from the file. Now it employes the same hashing mechanism and generates its own set of hashes. If these two hashes match the ones with the file downloaded, then the browser kn...

Homomorphic encryption

Image
Homomorphic encryption is a type of encryption where the data in transit can be accessed, computed, analysed all the while the data remains encrypted. This can be extension of both symmetric and asymmetric encryption(See Symmetric and Asymmetric Encryption for more details). This can be used for outsourcing encrypted data for storage and computation to the cloud environments In plain language homomorphic encryption is like this - Assume there are many things in a bag and you put your hands inside, manipulate their positions, access them and sense them but you cant pull them out and see for real what they are. This kind of data transmission is required in healthcare where the privacy is of most concern. The same holds good for voting purposes where the data needs to be encrypted for privacy purpose but also should be assessed. In the banking sectors too this is used to protect the PII and still perform the required processing on the data. The computations on the data are rep...
