Test Estimation/Factors to consider while providing estimation for testing a story, Planning Poker

Story Point Estimation technique used in Agile (Planning poker)

During the Sprint backlog meeting the stories are pulled from the product backlog into the Sprint backlog. The stories are then sized using Planning poker method in Agile.

The Planning Poker is a consensus based technique and is used to size the stories (in terms of story point) or effort estimate (in terms of days).

The following are the steps followed by the team while using the Planning Poker technique:

  1. Product Owner explains the story and its acceptance criteria in detail
  2. Team discusses the work involved and asks questions to the Product Owner
  3. Everyone estimates individually without getting influenced by others.
  4. Each team member selects a poker card that reflects their estimate of the effort required for that story
  5. Everyone reveals their estimates simultaneously.
  6. Team members who voted with the lowest and highest estimates explain their reasoning behind their estimation and any misunderstanding of scope is neutralized.
  7. After discussion, the team members reselect the cards to reflect their estimates based current discussion.
  8. Take the agreement of final number as the team estimate.
  9. Repeat the process for all the stories in the Sprint backlog.

POINTS/FACTORS TO CONSIDER AS A QA WHILE PROVIDING ESTIMATE FOR A STORY:

Test estimation means providing a rough estimate on time, effort and resources required to test the Story. 

While giving test estimation for a story, a Tester must consider all levels of STLC and the activities that are done in each phase.

i.e. Requirement anlysis, Test Planning, Test Design, Test Environment setup, Test execution and Test closure activities

Other factors to consider are

1. Time required for test environment setup.

2. Time required for test data setup.

3. Time required to analyse the story (i.e. Complexity of the story)

4. Time required for regression

5. Number of resources available to test the feature.

6. Communication (If a story is not fully finalized it may require to communicate on a large scale.

7. Retesting the bugs

8. Creating delivery documents like Test document.

   Jenkins Architecture: Jenkins follows a Master/Slave architecture where master and slave communicate over TCP/IP protocol Jenkins Architecture has 2 main components: 1. Jenkins Master/Server          2. Jenkins Slave/Node/Build Server 1. Jenkins Master: The Main Server of Jenkins i.e. the brains is the Jenkins Master It is a dashboard which is powered from a war file Runs on port 8080 by default With the help of the dashboard we can configure the jobs/projects but the build takes places in the Node/Slave server By default one node is configured and running in Jenkins Server We can add more nodes using IP addresses, username, passwords using jnlp, ssh or webstart methods The main job of server is: Scheduling build jobs Dispatching builds to the nodes/slaves for actual execution Monitoring the nodes/slaves Recording and Presenting the build results A Master/Server instance of Jenkins can execute build jobs as well i.e. it can also act as a node itself 2. Jenkins Slave: The Jenkins sla

Why do we need a build tool?

Why we need build tool? Consider this scenario where you want to run a java application   You can use java compiler (javac) provided by JDK to compile java code into Byte Code which can then run on any Machine To compile Java Programs using javac you will have to list all java source files to run the entire application Ex., "javac Program1.java Program2.java Program3.java Program4.java" This is a very tedious job. Doing this manually is a pain since there are hundreds of libraries used even in the simplest of Java Application Also one has to add Compilation classpath to make the code work. For example if the code uses libraries like testNG, Selenium etc. You need to add it to Compilation Classpath using following code: "javac -cp testNG.jar; webdriver.jar; lib3.jar" MyProgram.java In conclusion, Compiling java code manually becomes very tedious and complex task Enter Third party build tools like Spring boot, apache-comm
