Software Testing Types

This section describes the different types of testing that may be used to test a software during SDLC. Manual Testing Manual testing includes testing a software manually, i.e., without using any automated tool or any script. In this type, the tester takes over the role of an end-user and tests the software to identify any unexpected behavior or bug. There are different stages for manual testing such as unit testing, integration testing, system testing, and user acceptance testing. Testers use test plans, test cases, or test scenarios to test a software to ensure the completeness of testing. Manual testing also includes exploratory testing, as testers explore the software to identify errors in it. Automation Testing Automation testing, which is also known as Test Automation, is when the tester writes scripts and uses another software to test the product. This process involves automation of a manual process. Automation Testing is used to re-run the test scenarios that were pe...

What are the different Ways of doing Black Box testing? There are five methodologies most frequently used: Top down according to budget WBS (Work Breakdown Structure) Guess and gut feeling Early project data TPA (Test Point Analysis) Can you explain TPA analysis? TPA is a technique used to estimate test efforts for black box testing. Inputs for TPA are the counts derived from function points. Below are the features of TPA: Used to estimate only black box testing. Require function points as inputs. Can you explain the elementary process? Software applications are a combination of elementary processes. When elementary processes come together they form a software application. There are two types of elementary processes: Dynamic elementary Process:  The dynamic elementary process moves data from an internal application boundary to an external application boundary or vice-versa. Example: Input data screen where a user inputs data into the application. Data mov...

Six Sigma :: Software Testing

What is Six Sigma? Six Sigma is a statistical measure of variation in a process. We say a process has achieved Six Sigma if the quality is 3.4 DPMO (Defect per Million Opportunities). It's a problem-solving methodology that can be applied to a process to eliminate the root cause of defects and costs associated with it. Can you explain the different methodology for the execution and the design process stages in Six Sigma? The main focus of Six Sigma is to reduce defects and variations in the processes. DMAIC and DMADV are the models used in most Six Sigma initiatives.  DMADV is the model for designing processes while DMAIC is used for improving the process.  The DMADV model includes the following five steps: Define:  Determine the project goals and the requirements of customers (external and internal). Measure:  Assess customer needs and specifications. Analyze:  Examine process options to meet customer requirements. Design:  Develop the proces...
