How Do Best Software Testing Companies Measure Test Coverage
Test coverage is one of the metrics used for assessment of effectiveness and quality of a test process; it measures the degree to which the requirements or source code of software application is tested by a certain set of tests.
If we refer to software testing as evaluation of an actual and expected behavior of the system by means of final test suite, then namely this final test suite will be used to provide the test coverage:
The higher test coverage is required, the more tests are used to verify the requirements and the executable code.
Due to complexity of software products it is hardly possible even for the best software testing companies to achieve 100% code coverage. Nevertheless, it is possible to achieve the highest possible coverage using specially designed test suites, that is to say which are written and created with the help of specialized tools or test design techniques.
There are the following approaches to evaluation and measurement of test coverage:
Requirements coverage is a fundamental need during the entire development life cycle. It is a measure which describes the degree to which a test suite tests functional and non-functional requirements to software products. It helps to identify whether the application meets its requirements. Requirements coverage can be targeted using special tools and techniques. The goal of Traceability Matrix is to find out if all test cases are covered, without missing any functionality while testing. Some projects choose to follow a spreadsheet based on traceability matrix of requirements to different artifacts.
QA outsourcing is individual and impersonal compliance verification. Sending your project to third-party organizations for thorough and competent testing you protect yourself against unpredictable post releases expenses.
Code coverage metric is designed to assess the quality of the source code, namely to see how much of the code is being tested. It measures how thoroughly the program is exercised by tests. It is a measure applied to track which areas of app code are left untested.
Control flow-based coverage is a measurement of test coverage based on selection of a test case suite. This suite causes paths which are taken through the structure of the software so that to achieve a sort of control flow coverage.
Mobile testing companies use effective mobile testing strategies to provide as good test coverage for mobile apps as possible. They employ advanced test frameworks and test & code coverage tools to easily find untested parts of your programs’ code.
