How to Choose the best Testing Services?

Testing services – The measured look for the deserved leapRising competition and enhanced levels of regulatory compliance in the IT industry has necessitated that organizations ensure complete reliability on products being developed and deployed in the market. While the age old method of releasing products into the market and making changes based on customer feedback and on-site performance might have proven to be effective in the past, the current cut-throat business scenario is not salubrious to such practices. Gaining customers takes years, and losing them takes just a few minutes, and in releasing products with even the smallest of flaws several firms risk losing both existing and prospective customers. Apart from flaws in performance, testing services are designed to cater to several other aspects of the products in question. The need to ensure compliance with standards, proper certification and compatibility with different circumstances are all satisfied in employing the appropriate testing services.While there has been an explosive growth in technology and gadgets, there has also been, as a direct result, a significant drop in the tolerance rate in the global market for these products. The availability of scores of products to switch to is yet another reason for firms to ensure that they employ effective testing services to deal with the overwhelming possibility of loop-holes and errors that their products might exhibit. It all boils down to ensuring that the customer experience with your products is faultless and smooth, while offering an experience that is as close to a utopian setting as achievable. It is to this effect, that firms include numerous features to their testing services, the likes of load testing, benchmark testing, stress testing, performance testing and reliability testing. Each one of these processes go a long way in ensuring that the products have great scope in terms of prospective customers, and in offering the current customers a satisfactory user experience.The leap – Returns on investmentsTesting services have always proven to be the means to an end, in the monetary sense. In the managerial level, one of the key focuses is to ensure that investments made by a firm offer significant returns. When it comes to testing investments, the returns are to be expected are not direct and immediate. However, such investments prove to be a catalyst that maintains the returns that are brought in by the products for which the testing services have been employed, and as does any good catalyst function, even enhances the returns by having ensured flawless functioning and satisfied customers. Thus, while testing are not a direct source of returns, they are without doubt crucial step in ensuring that the products are completely reliable in both the revenue and the customers that they bring in to the firms.The measure – Identifying service providersThe growth of competition is a factor that puts to test, even the firms offering testing services. However, facing such competition or rather even ignoring it to be a threat is possible only when one has the competence and the confidence to do so. As is obvious, when it comes to the processes and tools utilized for testing, the room for flaws is non-existent. The process involves a selected few testing professionals simulating the experience of billions of users from different parts of the world, while taking into account factors the likes of varying knowledge levels, skills, attitudes and expectations from the product. Executing such processes, while ensuring reduced time to market for the products that are being tested is a feat that is accomplished only by a distinguished lot in the field. Thus, in opting for these services, one ought to look for such accomplished and renowned firms to ensure that their investment makes sense.The measure – Employing the right toolsAs a customer, your decision process ends with choosing the most consistent and trusted of firms offering the testing services, and this is when ours begins. The diversity of test suites that we possess is designed to cater to the ever growing range of products in the IT industry and in its diversity ensure that we have the perfect suite to cater to a specific product. Such choices ensure that the time taken for the testing process and eventually for the products to be released to the market is reduced by a great deal, while at the same time reducing the cost involved.Standing out from the crowdBeing armed with a comprehensive suite of software testing services that are built upon in-depth vertical knowledge gathered from working with numerous customers from different industries has proven to be our USP, in gaining customers despite heavy competition from other firms. Besides, in ensuring that we are able to map our service delivery in a manner that caters to the evolving needs of the customers the testing service offer the necessary results, whenever the customers require the same. The agile testing processes and methodologies that are employed are complemented by the different testing labs with ready-to-use configurations which have proven to be extremely efficient in ensuring reduced time to market, for the products.When choices are made, contemplating such factors is decisive in ensuring that the investments made in testing services prove to be a lucrative move that help the products and the firms in a significant manner, in the long run.

How to Optimize Behavior Driven Development for Software Testing

According to Dan North, the creator of Behavior Driven Development frameworks like JBehave and RBehave, “Behavior Driven Development (BDD) is a second-generation, outside-in, pull-based, multiple-stakeholder, multiple-scale, high-automation, agile methodology. It describes a cycle of interactions with well-defined outputs, resulting in the delivery of working, tested software that matters. To put it in simpler terms, Behavior driven approach focusses on delivering agile software solutions that result in higher business yield with lesser flaws and better quality. Behavior driven approach encourages and facilitates higher collaboration between teams and respective stakeholders.How you can determine BDD Approach for your Testing processDespite the advantages of automated testing, it is not practically wise to automate all test scenarios, since there are costs involved with every automation effort.Some scenarios where one is better-off with manual testing are:If a test needs to be executed only for a few times.If the application is likely to change soon (especially in the case of GUI).If, during its lifetime, a test is less likely to find any new bugs.Creating scripts for automated testing requires time and effort. When the application undergoes changes, the test scripts also need to be changed accordingly, otherwise the tests break. Further, testing efforts are constrained by resources of time and number of test automation engineers. Hence, “Which scenarios to automate?”is a question that is as important as “How to automate ?”Let us examine these questions more closely:“Which scenarios to automate? “This relates to the business value of a feature in the application. Business Analysts are the right people to answer such questions.“How to automate?”Test Engineers are the best people for this task. Wouldn’t it be nice if these responsibilities could be delegated to the right people? This is where BDD comes into the picture. Using BDD, not only are these responsibilities delegated, but the features are also written in such a way, that all the stakeholders can discuss about it, before even a single piece of test automation code is actually written.Using ‘Behave’ framework for BDD approachBehave is a BDD tool that supports Python, which we are using for our automated-testing purposes.We have the following test environment- Application under test (AUT): Web application GUI developed using HTML5Scripting Language: PythonTesting Tool: SeleniumFor this test environment, “Behave” suited us perfectly.A Simple Demo for Behavior Driven TestingFor demonstration purpose, let us take an example of an application that checks whether a number is prime or not.Features DocumentThe Features document could look something like thisIt is written in simple English language. No technical knowledge is required to understand it.This language is known as “Ghecko”.In this Scenario Outline, a list of input and output values are provided. This specification says that, for each input_value, the expected output should be same as the corresponding output_value. E.g, when the input is 3, then the expected output is “Prime”. This list can be modified at anytime. Test case gets executed for each value in the list.The 1st scenario says that, for a non-integer input value “dummy”, application must throw a TypeError exceptionThe 2nd scenario says that, for a negative value like ‘-1’, the application should return “Neither Prime Nor Composite”.Several other scenarios can be described in a similar way.After all the stake holders agree upon the set of features to test and their priority, test-automation team starts the test method implementation.BDD Test Method TemplatesThe test engineer creates a structure as follows:All the feature files are placed inside “features” folder.The test-case implementation files are created inside “features/steps” folder.After executing “behave” command, behave generates templates for the test methods.For our prime number example, behave will generate templates as below:The Test Engineer uses these templates and implements them in a Python file, inside the “steps” folder.Test Method ImplementationAn implementation of the “Scenario Outline” looks like:Test automation team need not implement all the scenarios present in the feature file. It can be done on a priority-basis.ReportWhen behave is executed, it shows the results for all the implemented scenarios and provides template methods for the unimplemented ones.Other useful information present in the report include: Test-case Result : Passed or Failed along with the test-case parametersTest-case execution time.Count of features passed, failed and skipped.Count of scenarios passed, failed and skipped.Count of steps passed, failed and skipped.Total time taken for test-case execution.For our prime number example, after implementing only the scenario outline, the behave report looks likeFor the unimplemented steps, templates are provided in the report:Conclusion : BDD Approach Fosters Engineers and Stakeholders’ AlignmentBehavior-Driven approach tries to make test-scenarios easy to read and maintain. It aids in easy communication between engineers and business stakeholders. In real-world scenarios, where there are complex applications and numerous features to test, this approach becomes more significant. Some quick points to summarize:Readability countsIf the implementation is hard to explain, it’s a bad idea.If the implementation is easy to explain, it may be a good idea.

Q&A on Mobitaz Android Test Automation Webinar

On the fifth of June, 2014, we conducted a webinar on Mobitaz, Aziro (formerly MSys Technologies)’s Android test automation tool. In this webinar, a number of professionals from various companies on testing and general quality assurance participated. Needless to say it was a big success. It can be challenging for a quality analyst to choose the right mobile-functional-testing tool for his testing purposes. Manual testing or the use of automation tools with limited testing capabilities can be a hindrance in expediting the QA process. Mobitaz (Aziro (formerly MSys Technologies) Android test automation tool) team at Aziro (formerly MSys Technologies) explored the need for a device- and an OS-agnostic mobile testing tool which can give the assurance to a QA team that testing isn’t compromised and too much time is not taken in a QA cycle. Discussions made in the Mobitaz webinar will bring a massive change in the traditional automation technique/solutions. Some of the interesting discussions initiated by the quality assurance personnel from leading companies are as follows: Parallel execution Question: Does it mean that I can run a test made for Kit Kat on Gingerbread and ICS at the same time? Answer: Yes. Concurrent playback on Kit Kat, Gingerbread and Ice Cream Sandwich can be achieved through Mobitaz. Question: So, Mobitaz adapts to different android objects that differ between OSes? Like progress bar between Gingerbread and Kit Kat? Answer: Yes. This is something unique about Mobitaz. The tool can record a test case once and play it back across any Android device or OS version. Mobitaz has the intelligence to recognize objects with different Android versions. Through this capability, it can make successful parallel test executions. Advantages Q: What are the advantages of this Android test automation tool over other mobile automation tools in the market? A:We compare Mobitaz directly with other tools which offer a lab-based solution. A few of the advantages over other mobile testing tools are: Support for Android Custom components Android Web-View components Parallel execution Testing on real devices without rooting Detailed reporting with easy option to export and share to PDF format Key measurements of resources such as battery, CPU, memory etc. Mobile functional testing for Android versions from Gingerbread to the latest version Simplified licensing model Cost-effectiveness Script-less Testing Q: Does Mobitaz Android test automation tool require any scripting knowledge to create, execute, and generate reports? A: No. Mobitaz is a script-less test automation tool and does not require any programming knowledge for functional testing of mobile apps. Mobitaz has intelligence to manage test cases, through features such as Object Repo, Test Case Editor, Reports, etc.
