manual testing Difference between Test case, Test specification, Test procedure and Test design? Software Quality Assurance & Testing Stack Exchange

Even if we eliminate geographies, you and I could produce entirely different specifications (or any document). This is because what I perceive as necessary may not be crucial for you and vice-versa. You have to display a summary of the relationship of this document to other pertinent documents. These include relevant technical documentation, pre-requisite documents, and companion documents.

Non-technical people or resources besides software developers need help understanding these test specifications. The primary use of these developer-level test specifications is for future software developers to check the unit tests. Test specifications are ‘written guidelines’ instructing the testers to run specific test suites and skip some. The test case descriptions presented in this section test the requirements for a specific dialog, dialog messages, and message content in a single test case.

These specifications provide a basis for verification that the content and structure of messages used or generated during testing are correct (per the requirements). The standard formed part of the training syllabus of the ISEB Foundation and Practitioner Certificates in Software Testing promoted by the British Computer Society. ISTQB, following the formation of its own syllabus based on ISEB’s and Germany’s ASQF syllabi, also adopted IEEE 829 as the reference standard for software and system test documentation. They are written at the item level to be used by developers or item writers to create new versions of a test for different test-taking populations.

Drafting the proper and accurate test specifications is a significant part of the Software Testing Life Cycle. The reason is that although the test cases are efficient, the team will not generate the expected outcome if the testers fail to comprehend them correctly. In this process, the testers can understand the test cases by reading the test specifications.

Some methodologies recommend creating at least two test cases for each requirement. One of them should perform positive testing of a requirement and the other should perform negative testing (e.g., testing for invalid values or conditions). Written test cases should include a description of the functions to be tested and the preparation required to ensure that the test can be conducted. For a developer, software requirements specification (SRS) might be the first document to note down his understanding and convey it to the customer or other team members. For testers, the SRS document becomes a test design specification (TDS) that serves the same purpose but is focused purely on testing and is just for testers.

You must render information about the method the team will control and track the development and distribution of the Test Case specification. For each test input, you must mention the name, purpose, and description (such as accuracy and range of values, among others). This is to be followed by the source of the test input and the method you use to choose the test input. You have to indicate the type of the test input, that is, real or simulated. In this section, you must note the prerequisite test cases or scripts that can generate the test environment or input data that enables running this test case or script. Moreover, you also have to note the post-requisite test cases or scripts for which the test environment or input data is created when this test case or script runs.

1.1 DXFS Conformance

The focus of this section is on development of test documentation to test system interface specification compliance. During the test phase, the system interface implementation is tested against the requirements specified for the project. A complete treatment of the topic of software testing is beyond the scope of this guide, and hence, no attempt is made to show a complete test example. A test procedure specification is a document that specifies a sequence of actions for the execution of a test. Test procedure specification development can begin after the test cases and design are completed and approved.

Specifications have taken on many forms and have served multiple departments with different purposes. Using test design specification, you can simplify understanding of the current testing cycles. However, to achieve the result, many things must flow correctly in creating specifications to make perfect sense.

What is the Test design specification?

You should consider the level for which the team has written the test case or script and accordingly describes the outputs. Some examples of these are human actions, tables, data (values, ranges, and sets), relationships (timing), files (transaction files, control files, and databases), and conditions (states), among others. You need to describe the input as text, an interface to another system, a file identifier, and a picture of a properly completed screen. You can use tables for data elements and values to simplify the documentation. The testing team develops the test specifications during the planning phase of software development.

test procedure specification

You should specify the minimum and maximum permissible test duration regarding the count of events or time. The maximum count of system breaks, halts, and interrupts that may occur should be mentioned. In that case, when they compare the test specification and the test assertion, the team can determine the reason for failure. Thus, the test specification is crucial to determine the cause of a test’s failure.

1.7 Pass/Fail Criteria:

One of the goals of Section 1201 was to realize national interoperability of systems providing real time information. To be conformant with the DXFS, a system implementation must be conformant with the underlying standards (TMDD, TCIP, SIRI, and OASIS CAP) upon which the DXFS is based. A system that does not conform with one or more of the standards is not conformant with the DXFS. This post by Harish Rajora is all about this document and breaking down these complex segments into simple and understandable concepts. Hope this guide provides a quick reference to build a robust test design specification for your next project. It is likely that we will encounter different viewpoints from different people across test design specifications.

  • These include relevant technical documentation, pre-requisite documents, and companion documents.
  • The earlier test specifications play the role of a guide for comparison between the previous versions of a test and the new versions.
  • You can refer to the System Design Document (SDD), Requirements Document, and High-level Technical Design Concept for these diagrams.
  • Though the diagram in Figure 4 shows a separate test design document for each test phase, a typical implementation will bundle the test design information with the test plan information, organized by test phase.
  • Besides defining the methodologies and standard procedures, project-based questions can consume most of your time.
  • To sum up, Test Case Specification defines the exact set up and inputs for one Test Case.

The test logs and test incident reports are then used to generate a test plan summary report. Tailoring the DXFS for a specific project was described in Sections 2 through 4 of this report. The end-result is a specification of requirements and design tailored to satisfy specific project needs for a RTSMIP implementation. The NRTM was designed to allow a project to develop a needs-based specification.

You should know the conditions for which you must interpret the output as indicative of abnormalities in the input test data, test procedures, or test data files or database. The final point is to note the permissible indications for the test’s results, status, control, and readiness to conduct the next test case or script. This is to be coupled with other pertinent criteria about the test case or script.
