Software Testing Types

Smoke Testing: A good starting point that is just a simple procedure. Without requiring much time or effort, a test like this allows you to determine if the product is ready for more detailed testing. This got its name from traditional hardware testing, where testers would turn on the product just to see if it would catch fire.  

Black Box Testing: Testers don’t know anything about the internal design or coding for this process. The focus is on requirements and functionality.  

White Box Testing: Here the testers actually know all the details behind the internal design and codes to the application. This helps them work on the coverage of code statements, branches, paths, and conditions. White Box Testing may be referred to as Glass Box Testing. 

Unit Testing: The individual parts of the software are approached separately in these tests. Because a perfect knowledge of the internal program is essential, the test is typically reserved for the programmer. Test driver modules or a test harness might be needed to complete this process. 

Incremental Integration Testing: This is a bottom up approach, with continuous testing of the application as functionality is added in pieces. This can be accomplished by either the programmers or testers. 

Integration Testing: This checks the combined functionality after the integration process. Code modules, individual applications, client and server applications on a network are all involved with this. This especially is crucial for client/server and distributed systems. 

Functional Testing: While completely ignoring the internal aspects, this zeroes in on the output using black box strategy. You can use this to validate an application, make sure a Web site meets specifications, or the product does everything it’s intended to. A series of tests are used for this, using normal and bad data. The product’s interface, APIs, database management, security, installation, networking, and other components are all involved. Some of the testing can be done with automated tools. 

System Testing: This checks the entire system against requirements. 

End-to-end Testing: Along the lines of system testing, this analyzes the complete application environment, exposing it to realistic situations. This includes interactions with databases, using network communications, and interacting with other hardware, applications, or systems. 

Sanity Testing: This is an easy and fast test just used to decide if the software can stand up to more extensive testing. If too much crashing or corruption is occurring, then immediate improvements are made.  

Regression Testing: This completed after changes have been made. It covers the entire system, so it’s generally done with automation tools. It accurately proves that defects have been completely resolved for the upcoming release, and also that no new problems were created during the modifications.  

Acceptance Testing: This simply gathers the customers? opinions to make sure it meets their standards. Acceptance Testing is only done by users or customers that haven’t been involved with the product previously.  

Load Testing: This observes what the system does under a heavy load. Testers look to see at what exact point the product begins to lose efficiency or fail. This is a broad term that covers Performance Testing and Stress Testing.  

Performance Testing: This assures that the system matches the performance requirements.  The tools used in these tests allow you to understand your application or WWW site’s scalability. You can also get a point of reference in an environment of third party products, like servers and middleware. Automated tools are crucial for doing these tests quickly and efficiently. 

Stress Testing: Stress greater than the specifications is introduced to the system, so that testers can understand the exact point it will fail. Inputting large numbers that exceed storage capacity, using complex database queries, and having continuous input is used to achieve this. The ideal result is an elegant degradation without catastrophic failure.  

Usability Testing:This checks the ease of use. Making sure that the application is easy to follow and has clear help documented throughout is essential for customer happiness.  

Install/Uninstall Testing: Using a variety of operating systems with different hardware and software, the product is fully installed, partially installed, upgraded, and uninstalled. The product should respond the same in all environments. 

Recovery Testing: This sees how fast and well the system is able to recover after crashes, failures with the hardware, and other major malfunctions. 

Security Testing: This makes sure that hacks aren’t able to access the system. Unauthorized internal or external access is considered, so that it can be prevented.  

Compatibility Testing: Using different combinations of hardware, software, operating systems, and networks, the testers make sure that the product is consistently flawless. It’s possible to do this manually, but easier with automated or regression suite tools. 

Comparison Testing: The product is analyzed based on standards created by existing products already on the market.  

Alpha Testing: This is user testing done under the supervision of the testers. It happens as one of the very last steps, with only minor design changes under consideration. 

Beta Testing: The product is released as a beta version, for users to try on their own sites. If any errors are found, the users send in the results.
