1. INTRODUCTION Now a day software development processes are becoming large and complex. Several activities are involved in the development of a large software products. To meet the desired requirement, these activities need to be suitably co-ordinate. Software testing is a process which often considered as an expensive and uncontrollable . Software testing is not used for preventing the bugs, but searching for the symptoms caused by the bugs. It is a process by which we executes the system to identify gaps, errors or missing requirements. Software testing is a process of planning, preparing, executing and analyzing the differences between the actual status and required status. Presence of the errors/faults are shown by the software testing. …show more content…
Whenever modifications are done in this phase retesting of software application is required. The process of retesting such a software is called regression testing. Regression testing is a type of software testing that seeks to check that the changes made to a system have not introduced new faults in the system. Though regression testing is expensive, it is necessary to perform it on the modified software. A consistent, repeatable validation of each changes made in the applications, are provided by the regression testing. During regression testing, new functionality may be added to the modified software or module to improve it’s response time. Regression testing involves re-testing of an application or system that has been modified to insure that no previously working components, functions or features fails as result of the repairs. Regression testing is executed parallel with other tests. It ensures whether the newly modified code compiles with it’s specified requirement, as well as unmodified code has not been affected by the changes. Novel test cases are not produced during Regression testing however formally created test cases are re-executed. To run all test cases for validating the adapted program is the most simplest …show more content…
When the test cases grow in number due to the growth of applications, it turns into very hard to implement all the test cases inside a particular amount of time. Test case selection deals with the execution of relevant test cases to find the changes between the previous and the current build of application. Test case prioritization is significant in regression testing. Test case prioritization techniques are scheduled over test cases in an order to improves the performance of regression testing. Test case prioritization works on the priorities based on the importance and the customer usage. Test case prioritization technique schedules the test cases for execution so that the test cases with higher priority executed before lower priority. The objective of test case prioritization is to detect fault as early as possible. The test case prioritization is classified into three categorizes • Priority-0: These test cases are Sanity test cases which checks the basic functionality and run for accepting the build for further testing. These test cases deliver a very high project value to both development teams and to customer. • Priority-1: It uses the basic and normal setup and these test cases deliver high project value to both development teams and to
The project is going I am working is almost in the finish stage it is going into the production phase means getting to the live so that the users can able to use the application. After the developing the total code it will go to the testing phase where the testers will check the code is working properly without any errors actually the testers task is to check the code and submit to the developers if they found any errors or mistakes or else they will send the code to the production phase to deploy in the server to check the application.
4. Explain why change is inevitable in complex systems and give examples (apart from prototyping and incremental delivery) of software process activities that help predict changes and make the software being developed more resilient to change.
My role in Saibersys Inc is QA Analyst. During my last weeks of internship we have started automation testing which means using automation tools for executing test cases suite. We usually prefer automation testing because it increases speed of test execution and test coverage. Well we have various types of automation testing tools and they are Selenium, QTP, Rational root etc. The tool we are using in our project is Selenium.

Abstract— Software testing is very important element in various product accuracy. Software testing is set of activities conducted with the intent of finding errors in software. It also verifies and validate whether the program is working correctly with no bugs no not. There are basically three levels of testing- Unit, Integration and System. Unit testing referred to as testing in small whereas Integration and System testing are referred to as testing in large. Various testing techniques available for designing of test cases. This paper basically deals with various techniques available to design software testing test cases.
Once an application is in testing stage, it is very difficult to go back and change something that was not well thought out in the concept stage.
To increase software quality, developers must thoroughly test their code early in the development process. Bugs must be caught and r...
The aim of testing is to ensure that business operations are not impacted and downtime is limited/avoided. The software update process should succeed on the test environment, and should be without major issues. Applications that were running before the update should continue to operate without any issues and should the update cause any problems it should be removed successfully.
The software testing is the critical element of software quality assurance and represents the Ultimate review of the software design and coding. The main objective of testing is to find an error and to uncover the errors that are not yet discovered.
This paper has the intention to explain what Rational Unified Process (RUP) is like an IBM product and a CASE tool. After is explained what phases it has, what are the most common extensions thus what are its workflows more used. The Rational Unified Process (RUP) is a software design method created by the Rational Software Corporation and now is part of IBM developer software. This paper describes how to deploy software effectively. The Rational Unified Process (RUP) use commercially proven techniques, and is a heavy weight process, and hence particularly applicable to larger software development teams working on large projects.
Once an application is in the testing stage, it is very difficult to go back and change something that need to be changed.
Integration testing comes before system testing and after unit testing has been completed. The integration testing stage will make developers aware of any errors produced due to the system or the script. The integration testing phase seeks to confirm that the integration of the components is fruitful and that it runs effectively, devise a test plan, and collect test case data produced to efficiently test that the integration is efficacious.
The initial step is to make a test and add it to the test suite. The primary motto is to make the code fail and pass after making certain changes to it. After the case has passed, another set of tests are being added and dealt in the same fashion one at a time. So one requires basic understanding of ...
Software development follows a specific life cycle that starts with designing a solution to a problem and implementing it. Software testing is part of this software life cycle that involves verifying if each unit implemented meets the specifications of the design. Even with careful testing of hundreds or thousands of variables and code statements, users of software find bugs. “Software testing is arguably the least understood part of the development process” and is also a “time-consuming process that requires technical sophistication and proper planning” (Whittaker 71) It is important to comprehend this concept by understanding the different characteristics and aspects of software testing, and then to examine the techniques, procedures and tools used to apply this concept. This will enable the user to realize the problems faced by software testers and the importance of software testing.
The three main criteria that are most important in a quality system are as follows:
