Also, the QA manager designs a KPI suite, including such software testing KPIs as the number of test cases created and run per iteration, the number of defects found per iteration, the number of rejected defects, overall test coverage, defect leakage, and more.
Besides, a risk mitigation plan should be created to address possible quality risks in big data application testing. At this stage, you should outline scenarios and schedules for the communication between the development and testing teams.
Preparation for the big data testing process will differ based on the sourcing model you opt for: in-house testing or outsourced testing.
If you opt for in-house big data app testing, your QA manager outlines a big data testing approach, creates a big data application test strategy and plan, estimates required efforts, arranges training for test engineers and recruits additional QA talents.
The first team, which consists of the talents who have experience in testing event-driven systems, non-relational database testing, and more, caters to the operational part of the big data application.
The second team takes care of the analytical component of the app and comprises talents with experience in big data DWH, analytics middleware and workflows testing.
In our projects, for each of the big data testing teams we assign an automated testing lead to design a test automation architecture, select and configure fitting test automation tools and frameworks. If you lack in-house QA resources to perform big data application testing, you can turn to outsourcing.
To choose a reliable vendor, you should:. ScienceSoft's tip : If a shortlisted vendor lacks some relevant competency, you may consider multi-sourcing. During big data application testing, your QA manager should regularly measure the outsourced big data testing progress against the outlined KPIs and mitigate possible communication issues.
Big data app testing can be launched when a test environment and test data management system is set up. Still, with the test environment not fully replicating the production mode, make sure it provides high capacity distributed storage to run tests at different scale and granularity levels.
Our cooperation with ScienceSoft was a result of a competition with another testing company where the focus was not only on quantity of testing, but very much on quality and the communication with the testers.
ScienceSoft came out as the clear winner. We have worked with the team in very close cooperation ever since and value the professional as well as flexible attitude towards testing. Testing a big data application comprising the analytical and the operational part usually requires two corresponding testing teams.
Below we describe typical testing project roles relevant for both teams. Their specific competencies will differ and depend on the architectural patterns and technologies used within the two big data application parts.
Note : the actual number of test automation engineers and test engineers will be subject to the number of the app's components and workflows complexity.
A professional testing team of balanced number and qualifications along with transparent quotes makes the QA and testing budget coherent and predictable. The testing budget for each big data application is different due to its specific characteristics determining the testing scope.
Additionally, either for outsourced or in-house big data application testing, you should factor in the cost of employed tools e. ScienceSoft will scrutinize your big data application requirements to provide a detailed calculation of testing costs and ROI. ScienceSoft is a global IT consulting, software development, and QA company headquartered in McKinney, TX, US.

| Big Data Testing: A Perfect Guide You Need to Follow | Load tests are the most popular performance test, but there are many tests designed to provide different data and insights. Load tests apply an ordinary amount of stress to an application to see how it performs. For example, you may load test an ecommerce application using traffic levels that you've seen during Black Friday or other peak holidays. The goal is to identify any bottlenecks that might arise and address them before new code is deployed. In the DevOps process, load tests are often run alongside functional tests in a continuous integration and deployment pipeline to catch any issues early. Stress tests are designed to break the application rather than address bottlenecks. It helps you understand its limits by applying unrealistic or unlikely load scenarios. By deliberately inducing failures, you can analyze the risks involved at various break points and adjust the application to make it break more gracefully at key junctures. These tests are usually run on a periodic basis rather than within a DevOps pipeline. For example, you may run a stress test after implementing performance improvements. Spike tests apply a sudden change in load to identify weaknesses within the application and underlying infrastructure. These tests are often extreme increments or decrements rather than a build-up in load. The goal is to see if all aspects of the system, including server and database, can handle sudden bursts in demand. These tests are usually run prior to big events. For instance, an ecommerce website might run a spike test before Black Friday. Endurance tests, also known as soak tests, keep an application under load over an extended period of time to see how it degrades. Oftentimes, an application might handle a short-term increase in load, but memory leaks or other issues could degrade performance over time. The goal is to identify and address these bottlenecks before they reach production. These tests may be run parallel to a continuous integration pipeline, but their lengthy runtimes mean they may not be run as frequently as load tests. Scalability tests measure an application's performance when certain elements are scaled up or down. For example, an e-commerce application might test what happens when the number of new customer sign-ups increases or how a decrease in new orders could impact resource usage. They might run at the hardware, software or database level. Also known as flood tests, measure how well an application responds to large volumes of data in the database. In addition to simulating network requests, a database is vastly expanded to see if there's an impact with database queries or accessibility with an increase in network requests. Basically it tries to uncover difficult-to-spot bottlenecks. These tests are usually run before an application expects to see an increase in database size. For instance, an ecommerce application might run the test before adding new products. If you're testing dynamic data, you may need to capture and store dynamic values from the server to use in later requests. The entire process quickly becomes too time-consuming and brittle to use within an Agile environment. LoadNinja makes it easy to record and playback browser-based tests within minutes with no coding or correlation. Navigation timings and other data are sourced from real browsers to make debugging a lot faster. For instance, test engineers or developers can dive into a specific virtual user that experienced an issue and debug directly from the DOM, providing much greater insights than protocol-based tests. And find that the factors are available. Also, proof the processed output data. In the result proofing makes sure that the transformation rules are implemented accurately. Fill the information in the target system. Also, make sure that the data in the output and in the HDFS has no fraud. Learn about Data Analytics tools in-depth with Data Analysis process. Hadoop is the data storage of an immense set of data with high standard arrangement and security. If the architecture of such big data is not taken cared of, then it will obviously lead to dreadful conditions of performance and the pre-determined situation may not be met. So the testing should always occur in the Hadoop atmosphere only. Testing of the concert includes the clear output completion, use of proper storage, throughput, and system commodities. Data processing is flawless and it needs to be proved. Interested in Data Analytics? Enroll in Data Analytics Training Courses in Bangalore to learn from the experts.
