Software testing words stamp in blue grunge look, little 3d men checking out for software bugs with magnifying lens. Choose us your Indian software development partner and get world class software developed at an affordable price. Testing is an extremely crucial phase of the software development life cycle (SDLC) and developers today face most demanding customers who expect 100% flawless functioning of the applications in use. Our Test Automation strategy is based on the principle that Test Automation complements manual testing rather than replacing it completely.This strategy involves identifying appropriate stages at which automation is introduced, selection of tools, scripting methodology and architecture of the script. Our data driven automation scripting approach is independent of UI changes to the application under testing. As a software tester, you have probably been asked at one time or another about whether you are doing “Verification” or “Validation”.
In other words, validation is checking that the system will meet the customer’s needs while verification is checking whether the system is well-engineered, without error, etc. Verification will help to determine whether the software is of high quality, but it will not ensure that the system is useful. An analysis of the requirements is carried out, so that the testing team can be well versed with the software that has been developed. Software Testing is the set of activities that involves Planning and preparing on how to test & what to test the software for and Executing software with the intent of finding defects and validating the software against requirements. Testing involves operation of a system or application under controlled conditions and evaluating the results. Faults in software are can be due to various reasons, from a simple typo to incorrect implementation of requirement or functionality that is not working fully or partially. 1.  A bug in the code radiation therapy machine caused loss of lives of 5 patients in 1980s as the device administered excessive quantities of X-rays than the quantity it was supposed to deliver.
The classes of errors detected by Black box and white box testing methods are different, however these 2 types of software testing methods complement one another. Below are the list of Software Testing Artifacts created during various stages of Software Testing Life Cycle. Software testing validates software against requirements, Software Quality assurance verifies if the defined Software testing processes are followed and Software Testing deliverables are created, reviewed as per the defined processes.  Software Quality assurance and software testing teams have different responsibilities but motto of both the teams is Quality.
There have been many myths and misconceptions about Software Testing.  Below are some of the most common myths. There are many certification bodies like QAI, ASQ, ISEB and ISTQB which offer Software Testing Certifications and Quality Assurance Certifications.  Exams are oriented to assess understanding of testing concepts but do not provide proficiency in Testing itself. In other words, your product should be free from technical anomalies – ensuring lesser number of complaints, greater customer satisfaction and optimum retention rates. The system requirements say there are two fields with max Length of 64 characters and Save button. Like the development phase has different phases, there are phases of testing life cycle as well.


It is process, which is carried to ensure that the software meets the specifications of the end user and is the software what the end user actually wanted. It is recommended that one spend a lot of time in this phase, to minimize headaches in the other software testing phases. It is in this phase that the types of testing to be carried out in the different phases of the testing life cycle are decided upon. If the testing activity starts along with the development activity of the software, the unit tests will also have been implemented in the development phase. Role of Software Testing is to detect these faults on time, report and get them fixed on time. Y2K (year 2000 problem) is a well known problem which induced fear of worldwide economic collapse.  Billions of dollars were spent in fixing the issue. In 1999 a major gaming company recalled copies of the game due to critical bug and had to apologize to its users. Unit Testing : Type of testing carried out by Software developers to test individual units of code or components or modules.
Functional Testing : Testing carried out by Software testing team to validate software functionality against requirements. Integration Testing : Type of Testing carried out by Software Testing team focusing on integration of modules and flow of data between applications. Sanity Testing : Type of testing carried out by Software Testing team to verify if the software is stable enough to carry our major testing. Smoke Testing : Type of testing carried out by Software Testing team to verify majority of the existing features are working fine in new build or version of the software given for testing.
Regression Testing : Type of testing carried out by Software Testing team to check if any of the existing functionality is broken due to code change or new code or defect fixes. Performance Testing : Type of testing carried out by Performance testing team to check performance, response time of the software.
Load Testing : Type of testing carried out by Performance testing team to check software behavior under load.
Usability Testing : Type of testing carried out by end users and Software Testing team to check how user friendly and easy is the software to use.
Compatibility Testing : Type of testing carried out by Software Testing team to find out if software is compatible on different environments or operating systems and with different web browsers for web based applications. Security Testing : Type of testing carried out by Software testing team to expose software’s vulnerability to hacks, brute force and unauthorized access. Stress Testing : Type of testing carried out by Performance testing team to check robustness and availability under heavy load. User Acceptance Testing : Type of testing carried out by client users to validate software against requirements. Recovery Testing : Type of testing carried out by Software testing team to test how software can recover from crash and hardware failures.


Software Testing is an Art, so hence some of the software test engineers are better than others.
Domain knowledge is required only for Software Testers and Business Analysts but not for Software Developers. There is no need for Software Testers to be involved during Software Design phase or Software design reviews.
Defects detected post implementation or only due to lack of time or resources provided to Software Testing team.
The software testing life cycle describes the testing activities, which are carried out on the software. The aim of the software testing activity is to identify, which are the testing activities to be carried out and when should they be carried out.
In some companies, testing start simultaneously with development, while in others, it starts after the software has been built.
In some cases, the test may have to be automated and in others, manual tests would have to be carried out. Often along with the unit tests, stress and performance test plans are generated in this phase.
If the bug has been accepted and fixed immediately, the software has to be retested to check if the bug has indeed been fixed.
The method in which the software testing activities are carried out will depend on how was the software developed.
Regression testing is carried out to ensure that no new bugs have been created in the software, while fixing of the bug. In some cases, the entire software is developed at one go while in some, it may be developed in small parts. Whatever be the method adopted for testing the software, the steps followed are more or less as mentioned below. If the test cases have to be automated, the suitable scripts for the same are designed at this stage. This helps in identifying bugs on the top level, which are then reported to the development team.
This matrix helps in analyzing, which of the test cases will have to be automated and which will have to be tested manually.
