Software Testing in Akurdi

What is Software Testing?

Software testing is an activity to check whether the actual results match the expected results and to ensure that the software system is Defect free. It involves execution of a software component or system component to evaluate one or more properties of interest.

Software testing also helps to identify errors, gaps or missing requirements in contrary to the actual requirements. It can be either done manually or using automated tools. Some prefer saying Software testing as a white box and Black Box Testing.

Types of Software Testing

Typically Testing is classified into three categories.

  • Functional Testing
  • Non-Functional Testing or Performance Testing
  • Maintenance (Regression and Maintenance)

Automation Testing

What is Automation Testing?

Manual Testing is performed by a human sitting in front of a computer carefully executing the test steps.

Automation Testing means using an automation tool to execute your test case suite.

The automation software can also enter test data into the System Under Test, compare expected and actual results and generate detailed test reports. Test Automation demands considerable investments of money and resources.

Successive development cycles will require execution of same test suite repeatedly. Using a test automation tool, it’s possible to record this test suite and re-play it as required. Once the test suite is automated, no human intervention is required. This improved ROI of Test Automation. The goal of Automation is to reduce the number of test cases to be run manually and not to eliminate Manual testing altogether.

Why Automated Testing?

Automated software testing is important due to following reasons:

  • Manual Testing of all workflows, all fields, all negative scenarios is time and money consuming
  • It is difficult to test for multilingual sites manually
  • Automation does not require Human intervention. You can run automated test unattended (overnight)
  • Automation increases the speed of test execution
  • Automation helps increase Test Coverage
  • Manual Testing can become boring and hence error-prone.

Which Test Cases to Automate?

Test cases to be automated can be selected using the following criterion to increase the automation ROI

  • High Risk – Business Critical test cases
  • Test cases that are repeatedly executed
  • Test Cases that are very tedious or difficult to perform manually
  • Test Cases which are time-consuming

The following category of test cases are not suitable for automation:

  • Test Cases that are newly designed and not executed manually at least once
  • Test Cases for which the requirements are frequently changing
  • Test cases which are executed on an ad-hoc basis.

Automated Testing Process:

Following steps are followed in an Automation Process

Test tool selection

Test Tool selection largely depends on the technology the Application Under Test is built on. For instance, QTP does not support Informatica. So QTP cannot be used for testing Informatica applications. It’s a good idea to conduct Proof of Concept of Tool on AUT.

Define the scope of Automation

The scope of automation is the area of your Application Under Test which will be automated. Following points help determine scope:

  • The features that are important for the business
  • Scenarios which have a large amount of data
  • Common functionalities across applications
  • Technical feasibility
  • The extent to which business components are reused
  • The complexity of test cases
  • Ability to use the same test cases for cross-browser testing

Automation Tool Best Practices

To get maximum ROI of automation, observe the following

  1. The scope of Automation needs to be determined in detail before the start of the project. This sets expectations from Automation right.
  2. Select the right automation tool: A tool must not be selected based on its popularity, but it’s fit to the automation requirements.
  3. Choose appropriate framework
  4. Scripting Standards- Standards have to be followed while writing the scripts for Automation. Some of them are-
    • Create uniform scripts, comments, and indentation of the code
    • Adequate Exception handling – How error is handled on system failure or unexpected behaviour of the application.
    • User-defined messages should be coded or standardized for Error Logging for testers to understand.
  5. Measure metrics- Success of automation cannot be determined by comparing the manual effort with the automation effort but by also capturing the following metrics.
    • Percent of defects found
    • The time required for automation testing for each and every release cycle
    • Minimal Time is taken for release
    • Customer Satisfaction Index
    • Productivity improvement
