Postman test cases on Jenkins

-

 1. Download and install postman - https://www.postman.com/downloads/ 

 2. Open postman and click on collection 

    Create new folder and start writing test cases -   






This will generate test suit for you ( postman collection for test cases )

3. Click on Environments and add key, value pair for the environment variables 

Example - We can specify environment details here so that same test case by changing env can be executed on multiple environments like - DEV, QA, UAT and PRD 

4. Now export postman collection and environment 

  1.     postman.collection.testcases.json 
  2.     postman.collection.env.json

5. Now install node js - https://nodejs.org/en/download

Install below node packages also - 

  1.     sudo npm install -g newman
  2.     sudo npm install -g newman-reporter-htmlextra

6. Now go to the folder where postman collection and environment json are store 
7. Run below commands - 

newman run postman.collection.testcases.json -e postman.collection.env.json -r htmlextra --reporter-htmlextra-export ./results/TEST-API.html


The above command will execute the postman collection and will generate HTML report for you. 

Now create a new job in Jenkins and add these command with postman collection.

Now all API test cases with execute automatically as per cron jobs on Jenkins

What’s the Difference Between Docker and Kubernetes?

    The most widely used tools in the modern cloud-native container ecosystem are Docker and Kubernetes . These two open platforms have enabled the container revolution to thrive, thanks to the utility they provide and the openness of their communities. Though often used together, Docker and Kubernetes accomplish different goals. This difference is foundational to understanding how modern containers are built, deployed and managed in production. The increase in container adoption has risen in parallel with the rise of microservices. Containers are a helpful way to package software for these applications as they isolate code with all dependencies necessary for runtime. But as the number of containers rises, managing them at scale becomes a hurdle. Thus, DevOps engineers often implement standard tools to generate containers and orchestrate their deployment to maximize efficiency and resource optimisation. For those readers with short attention spans, the TL;DR is that  Docker is about bu

Database Sharding

-
 What is Sharding? Sharding is a database architecture pattern related to horizontal partitioning — the practice of separating one table’s rows into multiple different tables, known as partitions. Each partition has the same schema and columns, but also entirely different rows. Likewise, the data held in each is unique and independent of the data held in other partitions. It can be helpful to think of horizontal partitioning in terms of how it relates to vertical partitioning. In a vertically-partitioned table, entire columns are separated out and put into new, distinct tables. The data held within one vertical partition is independent from the data in all the others, and each holds both distinct rows and columns. Should I Shard ?  Whether or not one should implement a sharded database architecture is almost always a matter of debate. Some see sharding as an inevitable outcome for databases that reach a certain size, while others see it as a headache that should be avoided unless it’s
