Let’s discuss some of the challenges in Big Data Testing

  • Data Harnessing (Cleansing)
    Challenge: Dealing with both structured and unstructured data which makes sampling strategy very difficult.
    Solution: Perform in-depth analysis of structured and unstructured data to convert them into a valuable format.
  • Data Quality & Completeness
    Challenge: It is difficult to make sure that complete data is pulled into the system pulled from various sources like RDBMS, weblogs, social media, etc
    Solution: Use tools like Presto, Talend and Datameer to verify the completeness of the data in HDFS.
  • Displaying Meaningful Results
    Challenge: Creating the BI reports from Big Data becomes difficult when dealing with extremely large amounts and diverse data.
    Solution: One way to resolve this is to cluster data into a higher-level view where smaller groups of data become visible.
  • Test Environment Setup
    Challenge: Creating an effective test environment, multiple testing nodes for Big Data testing.
    Solution: Take care of the environment to handle the Big Data effectively and efficiently.
  • Performance Testing
    Challenge:Faster data processing, work load, and network load balancing to ensure real time data synchronization.
    Solution:Have good infrastructure to store and process large amount of data in given time intervals to meet the performance.

Demanding features of RPA in Test Automation

  • Code-less: No programming skills required
  • Adaptable: Possible to schedule monitoring of work and can operate 24*7
  • Cost Saving: Huge cost reduction as a very minimal workforce is required
  • Accuracy: Bots governed by algorithms accurately perform actions
  • Flexibility: Platform independent. Supports a web-based, legacy, desktop, or mobile application
  • Scalability: Virtual workforce can be assigned anytime, and allows parallel execution
  • Data Migration and Change Management: Robots that work on legacy systems can easily be used to preserve the application’s data and integrity and they can also re-use the existing application logic, databases, and validation without high re-structuring or maintenance costs.
  • Cognitive Automation: RPA integrates structured and unstructured data using different AI features and extends the automation to more processes using cognitive capabilities for predictive analysis.

Let’s have a look at the differences between Test Automation & Robotic Process Automation.

Due to the outstanding features of RPA, organizations return the following benefits;

  • Cost Reduction: Bots are cost-effective since they save time and generate output with precision
  • Reduce errors & Enhance accuracy: RPA reduces the rate of human errors as mundane manual tasks are automated
  • Increased throughput and output: RPA testing supports the throughput of Big Data Testing that enhances the overall quality and maintenance of your end product even after it hits the market.

  1. Smoke Testing: Smoke Testing is used to check the stability of the product. QAOps leverages smoke testing for verification testing.
  2. Automated Testing: Automated Testing enables to testing of the software at a faster pace. This is leveraged by the QAOps framework by executing the automated codes as a part of the QAOps pipeline.
  3. Regression Testing: Regression Testing allows checking the reliability of the product when it is updated with a new feature or an existing feature is enhanced. QAOps checks if the quality of the software is maintained with the introduction of the new features or modifying the code.
  4. Parallel Testing: Parallel Testing allows running multiple test cases on an application and its subcomponents across operating systems and browsers for a product simultaneously which reduces the overall testing time. QAOps uses CI/CD pipeline for parallel testing which instantly enables faster testing.
  5. Scalability Testing: Scalability Testing depicts how the software will behave when the usage will increase or decrease in the longer run. The tests should be able to synchronize with the data and the process during scale up or down and we can achieve it via QAOps by leveraging scalability testing in the pipeline.

    Eg: surveillance robots and human-wearable biometrics for combat.
  4. Industrial Internet of Things (IIoT): Primarily used with industrial applications, such as in the manufacturing and energy sectors.
    Eg: Digital control systems, smart agriculture, and industrial big data.
  5. Infrastructure IoT: Primarily used for connectivity in smart cities.
    Eg: infrastructure sensors and management systems.

Let’s discuss some of the popular trends and scenarios of IoT testing:

  1. Artificial Intelligence (AI): The effect of AI in IoT testing can reduce extensive human hours and inaccuracies/discrepancies which results in ensuring a more reliable product. Testers can consider it to drive automation, expand coverage and enhance efficiency in all the areas of IoT testing.
  2. IoT Network Security Challenges: Securing the data and its privacy is very critical and authorizations play a very important role in IoT data streaming and transfer.
    It might be difficult to secure all the connected devices since the components or modules of IoT are not as simple as that of PCs and smartphones. Considering these security challenges in IoT, QA professionals must assess a full range of potential vulnerabilities in IoT products and services.
  3. Big Data Testing: The volume, value, variety, and variability of data generated by IoT systems and devices can be a huge challenge in IoT testing soon. Each type of data set requires different types of testing techniques and testers will have to adapt their testing skills accordingly.
  4. Micro Services Test Automation: Microservice architecture involves developing a single application that can work together as a suite of small services. When it comes to IoT, each of these services can run as an individual process and communicate with lightweight mechanisms such as an HTTP resource API.
    Utilizing Microservices for IoT testing will also offer the benefits of testing the extensibility, scalability, and integrations of the IoT system.
    Microservices test automation in IoT will reduce the complexity of testing a huge architecture as each microservice can be tested as a separate process.
  5. Testing For a Wide Range of Interfaces: Depending upon the type and number of connected IoT devices, it is necessary to test the integrations and interfaces to ensure appropriate coverage and universal functionality across all the touchpoints.
    If we consider the video streaming sites such as Netflix and Amazon Prime can be accessed on a variety of devices from HDTVs, smartphones to a gaming console.
    Therefore it is important to test the video streaming functionalities on all the platforms and connected devices are required to test on acceleration, vibration, stability, repetition, stress, memory, or endurance factors.
  6. Testing Wireless Connectivity Scenarios: Connectivity throughout the IoT network is dependent on many wireless standards like Wi-Fi, ZigBee, 4G LTE, etc. This will result in different wireless testing scenarios.
    Sometimes IoT devices could be out of range and so they will have to monitor the condition continuously. Therefore testing of various wireless scenarios will be an essential area to focus on IoT testing.
