Best software testing course in trichy

 Software testing is the process of evaluating and verifying that a software product or application does what it is supposed to do. The benefits of testing include preventing bugs, reducing development costs and improving performance.   

Types of software testing


There are many different types of software tests, each with specific objectives and strategies:

  • Acceptance testing: Verifying whether the whole system works as intended.
  • Integration testing: Ensuring that software components or functions operate together.
  • Unit testing: Validating that each software unit performs as expected. A unit is the smallest testable component of an application.
  • Functional testing: Checking functions by emulating business scenarios, based on functional requirements. Black-box testing is a common way to verify functions.
  • Performance testing: Testing how the software performs under different workloads. Load testing, for example, is used to evaluate performance under real-life load conditions.
  • Regression testing: Checking whether new features break or degrade functionality. Sanity testing can be used to verify menus, functions and commands at the surface level, when there is no time for a full regression test.
  • Stress testing: Testing how much strain the system can take before it fails. Considered to be a type of non-functional testing.
  • Usability testing: Validating how well a customer can

    use a system or web application to complete a task.

In each case, validating base requirements is a critical assessment. Just as important, exploratory testing helps a tester or testing team uncover hard-to-predict scenarios and situations that can lead to software errors.

Even a simple application can be subject to a large number and variety of tests. A test management plan helps to prioritize which types of testing provide the most value – given available time and resources. Testing effectiveness is optimized by running the fewest number of tests to find the largest number of defects.

History of software testing

Software testing arrived alongside the development of software, which had its beginnings just after the second world war. Computer scientist Tom Kilburn is credited with writing the first piece of software, which debuted on June 21, 1948, at the University of Manchester in England. It performed mathematical calculations using machine code instructions.

Debugging was the main testing method at the time and remained so for the next two decades. By the 1980s, development teams looked beyond isolating and fixing software bugs to testing applications in real-world settings. It set the stage for a broader view of testing, which encompassed a quality assurance process that was part of the software development life cycle.https://www.jalsedu.com/blog/soft.html

“In the 1990s, there was a transition from testing to a more comprehensive process called quality assurance, which covers the entire software development cycle and affects the processes of planning, design, creation and execution of test cases, support for existing test cases and test environments,” says Alexander Yaroshko in his post on the uTest developer site.

“Testing had reached a qualitatively new level, which led to the further development of methodologies, the emergence of powerful tools for managing the testing process and test automation tools.”

Data Analytics course in trichy

  Data analytics is the science of analyzing raw data to make conclusions about information. Many of the techniques and processes of data analytics have been automated into mechanical processes and   algorithms   that work over raw data for human consumption. KEY TAKEAWAYS Data analytics is the science of analyzing raw data to make conclusions about that information. Data analytics help a business optimize its performance, perform more efficiently, maximize profit, or make more strategically-guided decisions. The techniques and processes of data analytics have been automated into mechanical processes and algorithms that work over raw data for human consumption.  Various approaches to data analytics include looking at what happened (descriptive analytics), why something happened (diagnostic analytics), what is going to happen (predictive analytics), or what should be done next (prescriptive analytics). Data analytics relies on a variety of software tools including spr...

  The   HyperText Markup Language   or   HTML   is the standard   markup language   for documents designed to be displayed in a   web browser . It defines the meaning and structure of   web content . It is often assisted by technologies such as   Cascading Style Sheets   (CSS) and   scripting languages   such as   JavaScript . Web browsers  receive HTML documents from a  web server  or from local storage and  render  the documents into multimedia web pages. HTML describes the structure of a  web page   semantically  and originally included cues for its appearance. HTML elements  are the building blocks of HTML pages. With HTML constructs,  images  and other objects such as  interactive forms  may be embedded into the rendered page. HTML provides a means to create  structured documents  by denoting structural  semantics  for text such ...
