Data-driven test automation is the best mobile application testing strategy

Using software for execution of tests as well as determining whether the predicted outcome and actual outcome are same or not on basis of those tests is known as test automation. Automation phases in software appears during the testing as well as implementation phase. Automated testing helps organizations accomplish the goal of adequately tested software as fast and thoroughly as possible. The coverage is also increased and the need for testing manually is reduced. Through this type of evaluation, minor defects which remain unexposed by manual testing are discovered. In fact, there are plenty of other advantages associated with this kind of evaluation, making it absolutely indispensable in the world of software. This is especially so for testing of mobile applications since it is a much more complicated process with the number of varying platforms along with operating systems of tablets, smartphones, etc.

Automated tests need proper execution environment; in this case it is an automation or testing framework which is an overall system for the automation of tests. The framework or support or work platform for the evaluations constitutes a set of concepts, practices as well as assumptions. The framework is application independent and can be easily expanded, maintained and perpetuated. Testing frameworks are of different types- modular, keyword driven, hybrid and data driven.

For data driven testing, data files supply the test's output and input values. Separate files store the expected output and input results. Although, the file is generally in tabular formats, it can be a CVS file, Excel file, DAO object, ODBC source, ADO object, etc. In such a framework variables are used for output verification values along with input values. All coded information related to navigating through evaluation status logs and application, reading of data files, etc are there in evaluation scripts. The test case remains encapsulated in information files and scripts remain a means for data delivery or a “driver”. Just the test information is contained in the data files of this type of evaluation.

Data-driven testing framework has a number of advantages like-

• The scripts can be created even during the ongoing development of applications.
• You can greatly reduce unnecessary duplication as well as redundancy of automated test scripts creation because records and files are used for verification of data along with input and also because of the modular type design.
• When there arises changes in the functionality, all you need to do is revise the script of the specific “Business Function”.
• Details as well as information like expected results, outputs or inputs are stored in form of text records which can be managed very conveniently.
• Errors can be handled better which results in more robust testing scripts. This is mainly because during the calling of scripts the functions return with “FALSE” or “TRUE” values, the entire thing is not aborted. Just creating a nice “recovery” program results in the execution of test scripts without needing any attendance.

Data-driven frameworks have certain disadvantages as well. For the automation tool, you need to be an expert on the scripting language; for each test case, many data-files are needed. In fact, evaluation plan information has to be re-entered by test engineer in varying data-files and on top of that the test plan has to be properly managed as well. However, the advantages of data-driven test automation outnumbers the disadvantages. With this type of testing, new test cases can be easily added just by adding new entry into information source. Also different sets of information help cover many aspects of the features of applications, thus increasing the test coverage. One script can test application functionality which makes this automation framework the best mobile application testing strategy.
