Software Testing is a process to check the functionality of the application is working according to the customer or clients requirements or not and also ensure the developed product must be bug free. Then main focus of software testing is to identify bugs, deviation and missing requirements from the actual requirement. Tested software products ensures reliability, security and high performance which further results in time saving, cost effectiveness and customer satisfaction.
Importance of Software Testing
It is to ensure that delivered product should be flawless with high quality. It plays a vital role in software development life cycle. The testing is more important because it identifies bugs before delivering the product to the client. Properly tested software will be more reliable and do high performance.
Software testing is generally classified into two main broad categories: functional testing and non-functional testing.
It validates against the functional requirements/specifications by providing the appropriate input, verifying the output on the developed software system.
It mainly involves Black Box testing like Smoke Testing, Integration Testing, System Testing, User Acceptance Testing, Sanity, Localization, Globalization etc.
It is to validates against the non functional aspects such as performance, usability, reliability, etc of a software application.
The main purpose the non-functional testing should increase usability, efficiency, maintainability, and portability of the software product. It mainly involves Performance Testing, Endurance, Load, Stress, Security, Volume, Scalability, Stability etc.
|Sno.||Functional Testing||Non-Functional Testing|
|1.||Smoke Testing – It verifies the basic and critical functionalities of the software is working fine or not. It is to is done to check whether the received build is testable or not. It also known as Build Verification Testing, Skin Testing, Dry Run Testing.||Usability testing – Testing the user friendliness of an application [i.e] All the important features of the application should be exposed to the user first.|
|2.||Integration Testing – It verifies the data flow of the modules after validating that the module is working independently or not.||Compatibility testing – Testing the application on different software and hardware configuration or platform.|
|3.||System Testing – It is to verify the end to end flow of the software application to ensure that it is working fine as a whole system or not.||Performance testing – Checking the behavior of the application by applying load.|
|4.||User Acceptance Testing – Customer checks for the business scenarios or day today transaction or real time scenario. [i.e] How the user uses the application in his day to day life||Load Testing – Checking the behavior of an application by applying load less than or equal to the desired load is known as load testing.|
|5.||Sanity Testing – It is to verify that all the bugs have fixed and no other issues are a raised due to these changes made in the code functionality.||Stress Testing – Checking the behavior of an application by applying load greater than the desired load is known as stress testing|
|6.||Localization / LION Testing / L10N Testing – It is to verify the application for the different country formats.||Scalability Testing – Checking the behavior of an application by increasing or decreasing the load in a particular time interval is known as scalability testing.|
|7.||Globalization – Testing the application forxmultiple country languages (Internationalization ) and different country formats.||Stability Testing – Checking the ability of an application to withstand the load for a certain duration of time is known as stability testing.|
|8.||Regression Testing – Re-executing the old test cases across the multiple releases to make sure that the changes (such as addition, modification and division) has not effected the existing functionalities.||Volume Testing – Checking the behavior of an application by applying huge volume of load in terms of data is known as volume testing.|
|9.||Soak Testing /Endurance Testing – Checking the behavior of an application by applying load for a long duration of time in an environment which is not supportive is known as soak/endurance testing.|
Various methods to conduct the software testing types.
a. Black Box Testing – Testing is done by the test engineer where they check if the functionality of the application is working according to the customer or client's requirements or not.
b. White Box Testing / Glass Box Testing / Rear Box Testing / Structural Testing / Unit Testing -Testing done by the developer where they check each and every line of the code written by them before handing over the application to the Test engineer.
c. Grey Box testing – Testing done by the person who have the knowledge on application as well as coding
d. Adhoc Testing/ Monkey Testing – Testing without following any systematic approach were as we directly start testing the application however we want it. [i.e] Randomly
e. Exhaustive Testing – Testing for similar type of value continuously for a particular text box or field box
f. Exploratory Testing – Testing is done to explore the application knowledge by discovering, investigating and learning on each and every module of the application.
Phases of Software Testing
It is a procedural of activities followed during testing to ensure software quality expectation are met. Following are the major phases of Software Testing Life Cycle.
a. Requirement Gathering – QA Team studies requirement and interact with the stakeholder to understand the requirement.
b. Test Planning – Determines the Test Strategy, resource, test environment, and testing schedule.
c. Test Document – Identify the Test Scenarios (High level document – All possible combination to test the Application) and Prepare Test cases (detailed level document – Step by Step procedure to test the application) based on the identified scenarios.
d. Test Execution – It includes the execution of the test script, Identifying the bugs and reporting the bugs in bugs report and Requirement Traceability Matrix.
e. Test Cycle Closure – It involves test completion reporting, collection of test completion matrices and test results. The criteria for evaluating cycle completion is based on Time, Cost, Software etc. And need to prepare test closure report.
Software Testing Tools
Various testing tools are available to deliver a high-quality products. Some of the popular testing tools are below.
Automation Tools :
1. Selenium – It is Open source Testing framework used to perform testing on web application across multiple browsers and platforms like Windows, Mac, and Linux
2. Tricentis Tosca – Popular script-less tool to automate end-to-end testing for a software application.
3. HPE Unified Functional Testing – It is a functional GUI testing tool that allows the automation of user actions on a client-based computer application.
4. Ranorex – GUI testing tool execute automated tests defect-free throughout all environment and devices.
5. Appium – Open source mobile application UI testing framework. It allows native, hybrid, and web applications to test on emulators and simulators.
Defect Tracking Tool :
1. Zoho bug tracker – Flexible workflow for Issue trackers.
2. Bugzilla – Open source tool with features Email notification, reports, and charts, bugs generated in different formats, detect duplicate bug automatically, etc
3. JIRA – Captures and organizes the team issues, prioritizes the issue, and updates the status with the project.
4. HP ALM/ Quality Center – Complete test management tool with integrated bug tracking system.
5. Salesforce – Web-based bug tracking and project management tool which supports tasks planning, create stories to track tasks, reports, and statistics.
