SOFTWARE TESTING

INTORDUCTION

Software Testing is the process of evaluating and verifying the performance the functionality of software products or apps to ensure they meet expected requirements and are free from defects.

IMPORTANCE OF SOFTWARE TESTING

  • Product Reputation- Late delivery or software bugs can damage the brand’s reputation.
  • Customer Satisfaction- Testing helps to make sure that the software is free from bugs and that the product meets the customer’s requirements.
  • Uncovers Errors- The most severe defects from the customer’s point of view are those that cause the program to fail to meet its requirement.
  • Improves Software reliability- Software maintenacne and evolution can help you improve the reliability of your software by fixing bugs, errors and defects etc.
  • Performance- Determine how the stability, speed, scalability and responsiveness of an application holds up under a given workload. 

HISTORY OF SOFTWARE TESTING

  • Early Days(1950s-1960s)- Software testing began in the 1950s alongside the development of the first software programs.
  • Formalization of Testing(1970s)- The introduction of structured programming in the 1970s led to more formal testing methods.
  • Methodology and Tools(1980s)- The 1980s saw the advent of automated testing tools and more systematic approaches.
  • Agile and Continous Testing(2000s-Present)- The Agile Manifesto in 2001 brought iterative development, continous integration, and testing.

TYPES OF SOFTWARE TESTING

  • Manual testing
  • Automation testing

Manual Testing

Manual testing is a technique to test the software that is carried out using the functions and features of an application. In manual software carries out tests on the software by the following aset of predefined test cases.

ADVANTAGES OF MANUAL TESTING

  • Fast and Accurate visual Feedback
  • Less Expensive
  • No coding is Required

TYPES OF MANUAL TESTING

  • Black box testing
  • White box testing
  • Gray box testing

Black box testing
    Black box testing is a type of software testing in which the tester is not concerned with the internal knowledge or implementation details of the software but rather focuses on validating the functionality based on the provided specifications or requirements.

White box testing
    White box testing technique analyse the internal structures the used data structures, internal design, code structure, and the working of the software rather than just the functionality as in Black box testing.

Gray box testing
    Gray box testing is a method you can use to debug software and evaluate vulnerabilities. In this method, the tester has limited knowledge of the workings of the component being tested.

Automation testing
    Automation testing is the application of software tools to automate a human-driven manual process of reviewing and validating a software product.

TYPES OF AUTOMATION TESTING
  • Functional Testing
  • Non Functional Testing
  • Unit Testing

Functional Testing
    Functional Testing is a type of software testing in which the system is tested against the functional requirements and specfications. Functional testing ensures that the application properly satisfies the requirements or specification.

Non Functional Testing
    Non Functional Testing is a type of software testing that verifies non functional aspects of the products such as performance, stability and usability.

Unit Testing
    Unit Testing is the process where you test the smallest functional unit of code. Software testing helps ensure code quality, and it’s an integral part of software development. It’s a software development best practice to write software as small, functional units then write a unit test for each code unit.

ADVANTAGES OF SOFTWARE TESTING
  • Improved Software quality and reliability
  • Early Identification and fixing of defects
  • Improved customer satisfaction
  • Low failure

DISADVANTAGE OF SOFTWARE TESTING
  • Can be difficult to fully test complex system
  • Not all defects can be found
  • Time-consuming and adds to the project cost
  • This can slow down the development process

SOFTWARE TESTING TOOLS
    Software Testing tools are the tools that are used for the testing of software. Software testing tools are oftn used to assure firmness, thoroughness and performance in testing software products. Some Software testing tools are
  • Selenium
  • Appium
  • Ranorex
  • Cypress
  • Cucumber
  • Watir
  • Eggplant

APPLICATION OF SOFTWARE TESTING
  • Test Planning
  • Test Design
  • Test Excusion
  • Defect Retesting
  • Test Closure and Documentation

IMPORTANCE OF FUTURE SOFTWARE TESTING
  • All information about testing goals and processes used.
  • Industry benchmarks and standards.
  • Various testing measures and measurements.
  • Configuration contorl.
  • Deadlines and the schedule, including the processes of running tests.

CONCLUSION
    Software testing is the process of finding errors in thd development product. It also whether the real outcomes can match expected results, as well as aids in the identification of defects, missing requirements or gaps.
