What is Big Data Testing? Big Data Testing Tools and Types | W3Softech

Big Data Testing:

Big Data Testing is the process of testing applications which contains Big Data. Here, Big Data in the sense collection of large data sets that are too hard to handle by traditional data computing applications. Datasets involve a wide range of tools, techniques and frameworks to process the application testing. Performance Testing and Functional Testing are key elements of Big Data Testing.

In the process of this testing, testers need to verify the processing of terabytes of data using supportive components. It involves checking various characteristics such as accuracy, conformity, consistency, data completeness, duplication, validity, etc.,

Big Data Testing is divided into three steps

Step 1: Data Staging Validation

• In the first step, a large amount of data should be validated from a wide range of sources like RDBMS, Social Media, Weblogs, etc., to ensure that data is correctly pulled into the system
• It compares the data pushed into the Hadoop with the source data to ensure that they both are matching
• It helps to verify the data which is extracted and pushed into correct HDFS location

Step 2: MapReduce Validation

In the second step, QA engineers or testers need to verify the business logic validation among every node and need to validate them after running over multiple nodes. Here MapReduce validation works based on Map procedure which performs filtering and sorting whereas Reduce procedure performs a summary operation

• It ensures that application process works properly
• Implementing the data based on data aggregation rules
• Make sure validating the data after the process of MapReduce

Step 3: Output Validation Phase

The third step in big data testing is the output validation phase. In this final step, the output files are created and moved to a Data Warehouse system or to any other system depending on requirements

• It helps to check whether the transformation rules applied correctly or not
• It validates the data integrity and data load into the system
• Helps to ensure the data free from corruption by comparing the HDFS system data with target data

What is Cloud Testing? Cloud Testing Tools and Types | W3Softech

Cloud Testing

Cloud Testing is defined as the process of testing Cloud Computing Services like Software, Hardware and other Remote Services. It is one of the Types of Software Testing generally used to perform on all cloud testing services.

Objectives of Cloud Testing:

• The major objective is to reduce the execution time of testing for large applications
• It helps in reduction of cost
• More efficient and greater scalability
• Helps to increase the mobility

Cloud Computing is mainly divided into three categories namely IaaS, PaaS and SaaS

Infrastructure as a Service (IaaS):

The name itself says that it works on physical resources like storage, network devices, computing servers, etc., these resources are provided as per the user requirement. It is the first and most important category also called the building block of a cloud.

Platform as a Service (PaaS):

It is the second category of the cloud. It is also called as Application Platform as a Service or Platform Based Service. It helps customers to develop, run and manage applications without any interruption to OS and required middleware, etc.,

Software as a Service (SaaS):

Software as a Service also called On-demand software or Software plus services. It is the final category of cloud computing. It is simply defined as license-based software available to any user based on their required plan. Up to certain features, it is available for the free later user to need to pay and get full access. Examples are Windows OS, Adobe Photoshop, etc.,

Types of Cloud Testing - W3Softech

Types of Cloud Testing:

Cloud Testing is able to perform on both Functional Testing and Non-Functional Testing some of them are listed below

System Testing:

System Testing is performed to check whether all functions of the application are working properly or not under given system requirements

Interoperability Testing:

This testing determines the flexibility and compatibility of the application while changing from one infrastructure to other

Acceptance Testing:

It is the final stage of testing under functional testing to ensure that it meets the user expectations

Availability Testing:

Here the admin has to make sure that the cloud is available always as there may be sudden functions are going on which do not interrupt the user activity

Multi-Tenancy Testing:

This shows that the application should perform correctly while multiple users are trying to access the application at an instant time.

Performance Testing:

Performance Testing is of two types Load Testing and Stress Testing. It ensures that the application must accept the load and stress from N no. of user requests. To perform well the cloud need to have elasticity which increases the usage as required

Security Testing:

It helps to check the security of the cloud is accessible for only authorized users and data must be protected.

Disaster Recovery Testing:

As the data is available in cloud servers sometimes there may be a cause of system failure, data loss or extreme workload. So this testing helps to measure how fast the error got found and any data loss occurred.

Cloud Testing Tools:

What is Mobile Testing? Mobile App Testing Tools and Types | W3Sofetch

Mobile Testing

Mobile Testing can be defined as the process of testing the mobile devices to check the performance of developed software application usability, functionality and consistency. The Mobile App Testing can be done through either manually or automatically.

Mobile Testing Types:

Mobile Application Testing can be divided into two types namely Software Testing and Hardware Testing

Software Testing:

The process of testing the software application developed for mobile devices is known as Mobile Software Testing or Mobile Application Testing. Again this testing is divided into three parts

Native Apps: Native apps are apps created for general purpose usage on mobile platforms and tablets.

Mobile Web Apps: These apps are called server-side apps developed to access websites on mobile using various browsers such as Firefox, Chrome, etc.,

Hybrid Apps: These are the combination of the above two apps which can run on offline as they are developed using HTML5 and CSS

Hardware Testing:

This testing is used to perform on hardware parts of devices like internal processors, screen sizes, resolution, RAM, ROM, camera, Bluetooth, FM Radio, etc.,

Differences between Native Apps and Mobile Web Apps:

Native Apps	Mobile Web Apps
It has a single platform affinity	It has a cross-platform affinity
These are written in SDK format	These are written in HTML, CSS, PHP, etc.,
Only downloadable from play store or app store	Only accessible through the internet
It requires installation compulsory	No need for any installation
Can be updated from play store or app store	These are centralized updates
Most of the native apps don’t need an internet connection	For all mobile web apps, the internet is compulsory
Works faster	Works based on web technology used

Types of Mobile Testing:

Depending on the mobile testing types, below are the testing types which are used to perform on mobile devices

Usability Testing:

The name itself says that it is used to check the user experience of the developed mobile application. It should satisfy the user in terms of usability, flexibility and friendliness

Compatibility Testing:

This testing is usually performed on mobile devices to make sure that whether the developed mobile application is comfort with the device. To check that the developed app is compatible with mobile’s screen resolution, OS Versions, etc.,

Interface Testing:

Interface Testing helps to determine the performance of user interface like menu buttons, history, settings, bookmarks, etc.,

Interrupt Testing:

Interrupt Testing is the process of testing an application which may undergo interruption while using the mobile app. In simple words we can say that testing the developed mobile app while there may come interruptions like SMS, Calls, Web notifications, on/off the media player, etc.,

Memory Leakage Testing:

It helps to determine the optimization of the mobile app under limited memory. Thus, each developed application should work without making any memory leakage and satisfy the user.

Performance Testing:

Testing the performance of a mobile application which may go under various changes like data changes from mobile to wifi, low battery power consumption, network coverage, etc., Here testers need to perform testing on both sides of application such as server-side client side.

Operational Testing:

Operational Testing is the process of testing a mobile application’s backup or recovery functions if the user upgraded an app from a store.

Installation Testing:

Whenever a user is able to install, uninstall or upgrade the developed app this testing came into existence. The mobile app should satisfy the user while performing any of the above steps without interrupting.

Security Testing:

Security Testing is the process of testing to determine the security of the mobile app without losing any data. Here testers need to check the app whether it is working under given security guidelines and protecting the data.

What is Manual Testing? Types, Tools and Concept | W3Softech

Manual Testing is a type of software testing usually done by testers manually to perform test cases and find out the bugs or errors in a software system. Any software application before going under automation testing must be tested manually.

The major role of this testing is to ensure that the system is defect-free and working properly then let it go for the next step in the development life cycle. Name itself says that this testing is done by manually without using any automation tools.

Working Process of Manual Testing:

• The initial step is to study and analyze completely the project give
• To execute the test cases based upon the business requirements
• Perform testing manually to find out any bugs or defects in the software application and fix them
• Perform retesting by testers to find out any missing bugs in the system and fix them
• Finally, the project will go for the further step after successful completion of testing

Manual Testing

Advantages of Manual Testing:

• This Testing can be done through either functional or non-functional
• Any kind of software application or system can be tested manually

Disadvantages of Manual Testing:

• It requires human intervention
• It requires highly skilled testers and longtime process
• Based upon the above things it costs high
• The testing process will become repetitive so that may get boring
