Testing and QA Services

A good testing and QA services ensures to minimize the cost, mitigate risk, augment user experience levels by offering creative solutions to improve product life cycle.

Quality assurance is a systematic approach to check if the product designed, meets the specific requirements of the customer or not. Using independent leading testing and QA techniques to test the functionality, performance and security of the service or product can eliminate defects in the early stage of the development. Quality assurance and testing are designed to provide better functionality of a service or product to increase customer confidence and company creditability.

Automated Testing

Testing include automation of data creating test reports by comparing actual, expected and delivered test results. Automated testing's main objective is to reduce the test cases and make the service work successfully. This tool helps to record and report the actions of the software that can be compared with manual testing to analyze the performance rate. Manual testing requires a lot of effort and even after that, the errors do creep within. Automated testing has possibly opened the doors to perform tasks that are impossible and time-consuming through manual testing. Once the automated testing is created they can be repeated and extended whenever required.

Benefits of automated testing:

Saves time and money
Increases accuracy and coverage
Helps to detect the problem quickly

Selenium

Selenium is a software frame work designed for web applications. It is an automated test tool that records the authorizing tests by providing a specific domain-free language that helps to write these tests in different programming languages. Selenium is considered to be one of the best automated tools that is becoming increasingly popular. It is easy to use and very flexible to operate. The scripts of the selenium are recorded in special script language called selenese, that give commands in the browser to retrieve data from the web pages provided.

It supports various platforms like internet explorer, Firefox, Mac OS X, Linux etc. Selenium RC and IDE are core components of selenium that helps better integration of framed test work with different units. Selenium remote control is written in JavaScript that helps to write automated tests to web applications. Selenium IDE is an extension of Mozilla Firefox that is used to record tests and suits.

The functions of selenium automated tool:;

Helps to integrate with various units to run tests
Provides a record of entire browser session
Works with an http website (RC)
Helps to control supporting browsers
Allows cross browsing testing

Test Complete

Among the various automated software running parallelly in the market, test complete automation tool helps the testers to create, record and manually script the tests. This tool helps to automate different software test types. Test complete generally works on built-in keyword test editor used to record automated testing actions. Comparatively test runs fast and gives good coverage within low costs. It provides services to test, web servers, web pages, web services etc.

Test complete services include:

Integration testing
Regression testing
Data-driven testing
Functional testing
Load testing

Manual Testing

Manual testing is the oldest and most meticulous method of testing software wherein the testers do not use any automated tools. In this process, a tester manually works on the software testing for errors and defects before delivering it in the market. It is a tedious job and consumes a lot of time to completely check every single software.

Once the testing starts, the designed test cases and scenarios are tested by the tester. The difference between the actual and expected results are analyzed, compared and reported as defects. The ultimate goal of a tester is to deliver software of good quality to gain customer satisfaction. Manual testing has more draw backs than benefits. Manual testing cannot be done under multiple gateways. In manual testing, hidden information cannot be written using any program.

Manual testing services:

Acceptance testing
Integrated testing
Black box testing
White box testing
Unit testing
System testing

QTP

To address regressive test automation of software, QTP acts as a functional support in executing the tests. It is an automated graphical user interface testing tool which allows automation of web or customer-based computerized application. The test procedure of QTP is carried by VBscript. This scripting language of QTP specifies a testing procedure that helps manipulate and control the applications under tests. This tool identifies objects, application user interface and helps carry out desired changes. It generally follows key word driven approach. QTP have three types of recording modules, context sensitive, analog and low level.

Context sensitive: It is a basic default type of recording wherein the objects in the application are recognized regardless of the location. Once the object gets recorded in the application, the desired action gets performed on them.

Analog: QTP tracks and records every moment of the mouse when dragged around the screen. In analog module the tracks recorded can be stored in the directory of the tests. Analog recording can be done, relative to screen and relative to window. In the case of single window, the user can stick to relative screen. In the case of multiple windows, user can opt for relative windows.

Low level: Low level records are coordinate-based. A user uses low level recording if the test automation is precise to specific coordinates. It records every object of the application irrespective of QTP recognizing it or not. This consumes much of the disk space.

QTP services include:

Test script models
Test object models
Test data designing
Analyzing the checkpoints
QTP data recording
Keyword driven frameworks
Debugging and script enhancements
Script maintenance

The advantage of QTP is unlike other automated testing tools; QTP offers excellent recovery options through which the tests can be run through the point it stopped due to some accidental failure.
