software testing

DesignDot’s Software Testing Services are backed by a very competent team with a strong testing expertise. DesignDot has been widely acclaimed for its spectrum of testing services, quality of resources, wider delivery capabilities etc. Key services of DesignDot for Software Testing services include:

Guidelines

System & QA Testing Guidelines

  • Verify the interacting modules
  • Fulfill the Company's functional requirements
  • Human interface works as intended
  • All processing within constraints
  • All modules should be compatible, and upon failure degrade gracefully
  • Have sufficient procedures to provide disaster recovery
  • All operations procedures for the system are useful and complete

Developing QA & System Test

  • List all actions, functions, and transactions to be tested
  • Design transactions to test all actions, functions and transactions
  • Develop a single-user test script for above
  • Interleave the tests across the users participating in the test to fully test multi-user functioning of the application
  • Develop test scripts for each user
  • Conduct the test
  • Review test results and reconcile anomalous findings
  • After completion compile minimum set of transactions into regression test package

Once the site is tested successfully on Staging Server, it has to undergo a mandatory security audit before it is hosted on the production server. The Security auditing service has to be offered by the Service Provider to the Company.

Test Case Guidelines

  • Developed to verify that specific requirements or design are satisfied
  • Each component must be tested with at least two test cases: Success & Failure
  • All modules should be deliberately failed at least once to verify degradation
  • To ensure comprehensiveness, use methodical approach to identify logic paths or system components
  • Real data should be used to test the modules after successful test data is used
  • Test cases should be used to test multiple requirements.

Functional Testing

It is a type of black box testing that bases its test cases on the specifications of the software component under test. Functions are tested by feeding them input and examining the output, and internal program structure is rarely considered (unlike white-box testing)

Functional testing differs from system testing in that functional testing "verifies a program by checking it against ... design document(s) or specification(s)", while system testing "validate[s] a program by checking it against the published user or system requirements

DesignDot’s core testing team is well equipped to do any type of functional testing on a client’s software or software modules.

UNIT TESTING

It is a method by which individual units of source code, sets of one or more computer program modules together with associated control data, usage procedures, and operating procedures, are tested to determine if they are fit for use. In procedural programming a unit could be an entire module but is more commonly an individual function or procedure. In object-oriented programming a unit is often an entire interface, such as a class, but could be an individual method. Unit tests are created by programmers or occasionally by white box testers during the development process.

Unit testing can be time-consuming and tedious. It demands patience and thoroughness on the part of the development team. Rigorous documentation must be maintained. Unit testing must be done with an awareness that it may not be possible to test a unit for every input scenario that will occur when the program is run in a real-world environment.

SYSTEM (INTEGRATION) TESTING

This is a simple method which can be performed with minimum usage of the software testing tools. The usual steps involve exchanging some data imports and data exports, and then investigating the behaviour of each data field within each individual layer.

There are three main states of data flow after the software collaboration has been done. System Integration Testing will verify the process of synchronization between two or more software systems and can be performed after software system collaboration is completed.

REGRESSION TESTING

The intent of regression testing is to ensure that a change, such as a bugfix, did not introduce new faults. "One of the main reasons for regression testing is that it is often extremely difficult for a programmer to figure out how a change in one part of the software will echo in other parts of the software.

Common methods of regression testing include rerunning previously run tests and checking whether program behaviour has changed and whether previously fixed faults have re-emerged. Regression testing can be used to test a system efficiently by systematically selecting the appropriate minimum set of tests needed to adequately cover a particular change.

USABILITY TESTING

Usability testing focuses on measuring a human-made product's capacity to meet its intended purpose. Examples of products that commonly benefit from usability testing are foods, consumer products, web sites or web applications, computer interfaces, documents, and devices.

NON-FUNCTIONAL TESTING

Non-functional testing is the testing of a software application for its non-functional requirements. The names of many non-functional tests are often used interchangeably because of the overlap in scope between various non-functional requirements. For example, software performance is a broad term that includes many specific requirements like reliability and scalability.

PERFORMANCE, LOAD, VOLUME AND STRESS TESTING

Performance testing measures response times across various system layers, and identifies potential bottlenecks that may exist. Ideally, the system being tested is already functionally stable

Load testing is often a part of the larger performance testing strategy. It is different from performance testing, in that performance testing may measure response time with a single user exercising the system or with multiple users exercising the system. Load testing, however, focuses on increasing the load on the system to some stated or implied maximum load, to verify if the system can handle defined system boundaries.

Volume testing is often considered synonymous with load testing, yet volume testing focuses on data. Stress testing goes to the next level with respect to the number of users or data place in the system.

The intent is to go beyond testing stated or implied boundaries, and identify actual boundaries by identifying the precise load at which the system breaks (its resources are overwhelmed to the point it ceases to function properly)

TEST AUTOMATION

Test automation is the use of software to control the execution of tests, the comparison of actual outcomes to predicted outcomes, the setting up of test preconditions, and other test control and test reporting functions. Commonly, test automation involves automating a manual process already in place that uses a formalized testing process.

MANUAL TESTING

Manual testing is the process of manually testing software for defects. It requires a tester to play the role of an end user, and use most of all features of the application to ensure correct behaviour. To ensure completeness of testing, the tester often follows a written test plan that leads them through a set of important test cases.
