Explain Different Metrics Used in System Testing
Since quality is a subjective definition there are many different types of metrics used in software testing. Testing Metrics are mainly divided into 2 categories.

The simplest metric for model evaluation is.

. Types of Manual Test Metrics Base Metrics. Here is a list of 8 useful and effective software metrics the team must leverage 1. This data will be tracked throughout the Test Lifecycle.
Metrics simply measures quantitative assessment that focuses on countable values most commonly used for comparing and tracking performance of system. Thus for object-oriented projects different sets of metrics have been proposed. These are listed below.
They are used to measure cost quality and the products time-to-market. Various metrics such as time cost etc are collected by using the data from the projects in the past and they are used as an estimate for the new software. They include written and executed tests that aim to determine the softwares progress by QA Lead.
Lines of code and functional point metrics can be used for estimating object-oriented software projects. Alerting is the responsive component of a monitoring system that performs actions based on changes in metric values. The number of test case escapes is monitored as it rises.
For example Lines of Code LOC measure. However these metrics are not appropriate in the case of incremental software development as they do not provide adequate details for effort and schedule estimation. Of defect submitted100 2users requirement and software specification satisfied by system.
This testing makes sure that the functionality of a product is working as per the requirements specification within the capabilities of the system. Halstead measures can be used to derive metrics for testing effort. There are two different way to measure the test efficiency 1.
Metrics used for architectural design can be used to indicate how integration testing can be carried out. They are used to quantify defects cost schedule productivity and estimation of various project resources and deliverables. Here Ill discuss some common classification metrics used to evaluate models.
Product metrics describe the characteristics of the product such as size complexity design features performance and quality level. Identify the main issues that need to be tested. Alerts definitions are composed of two components.
They can help you to improve your projects lifecycle. It is defined as 22 matrix that tells about the performance of the model. Test Case Productive Prepration Total test steps effort hours eg TPP 608 75 8 test cases hour 2.
Object-oriented software engineering metrics are units of measurement that are used to characterize. Examples include the effectiveness of defect removal during. Process metrics can be used to improve software development and maintenance.
QA metrics in software testing. Planned versus Actual Execution PAE Rate. Test Execution Summary Summarize your reports with the following parameters such as Test Case Passed Test Case Failed Test Case Executed.
Internal metrics are the metrics used for measuring properties that are viewed to be of greater importance to a software developer. Product Metrics These are metrics that pertain to Product Quality. External metrics are the metrics used for measuring properties that are viewed to be of greater importance to the user eg portability reliability functionality usability etc.
Base metrics are data collected by analysts during test case development and execution. ITest Case Escapes TCE The test engineers may find the need to design new test cases during the testing called test case escapes as testing continues. In addition cyclomatic complexity can be used effectively as a metric in the basis-path testing to determine the number of test cases needed.
These are metrics that relate to Project Quality. Mean Time to Failure MTTF MTTF is described as the time interval between the two successive failures. Calculated metrics are derived using data from base metrics.
Some reliability metrics which can be used to quantify the reliability of the software product are as follows. It can be classified into three categories. Metrics are used in different scenarios like analyzing model design.
Product metrics process metrics and project metrics. The test lead gathers these data and. Object-oriented software engineering products eg designs source code and the test cases.
Below are the different types of testing which are as follows. The project manager checks the progress of the project from time to time and effort time and cost are compared with the original effort time and cost. By using program volume V and program level PLHalstead.
The common metric used to calculate the software testing efficiency are-Total number of defects identified in different type of testing-noof defects resolvedtotal no. An MTTF of 200 mean that one failure can be expected each 200-time units. The following metrics are useful in successfully tracking test projects.
Base Metrics are the Metrics that are derived from the data gathered by the Test Analyst during the test case development and execution. Different metrics that are used to measure performance of the model. Base Metrics Calculated Metrics Base Metrics.
Object-oriented software engineering processes eg designing and coding. A metrics-based condition or threshold and an action to perform when the values fall outside of the acceptable conditions.
