Agenda A. B. C. D. The testing landscape and its gaps Steps to industrialized testing How to tool up for industrialized testing with ModelDT Summary and further reading 2013-09 3 How to industrialize testing
A: The testing landscape and its gaps The development process is putting testing up the front There are many tools supporting the testing domain But there is a problem – the tools don’t talk to each others 2013-09 4 How to industrialize testing
The development process is putting testing up the front • • In the agile, Behaviour Driven Development, continuous delivery paradigms, test design comes before development. … therefore.. testing is even more closely integrate with business requirements User story User Test case Develop Backlog Test result Production 2013-09 5 How to industrialize testing
There are many tools supporting the testing domain MS Excel everywhere! • • • Testing is supported by many tools It has to be because testing's scope is 100% wide Many of the tools are excellent, with long, successful histories and wide adoption MD Testing specifications Continuous testing and integration Quality Center Requirements management, test management Behaviour driven testing Testing environment virtualisation Auto testing of business rules 2013-09 6 The testing profile and its
But there is a problem The tools do not talk to each other User Acceptance Risk Test plan Test management Test case Tester Test result Unit test System Under Test data Test Programmer Database User Operating model / User story Business process Test runner Project manager 2013-09 7 Test environment How to industrialize testing
B: Steps to industrialised testing 1. Adopt the vision and mental model 2. Implement four big ideas 3. Continuous learning and improvement 2013-09 8 How to industrialize testing
1. Adopting the vision What good testing looks like Tests are 100% aligned to the requirements (even when things change) Guaranteed correct Fast (=automated) Cheap (=automated) Industrialization: Conversion to the methods, aims, and ideals of industry and economic activity, particularly of an area that was previously underdeveloped 2013-09 9 Fully visible – at the tester level Well governed and managed How to industrialize testing
The model driven testing mental model 1: Separation of concerns, with each concern well managed. 2: Testing analysis and design is supported with specific tools. language and designs. Architect Design Build 2013-09 10 How to industrialize testing
2. Implement four big ideas • • • • Big idea 1: Industrialise your understand of your business Big idea 2: Industrialise the design of your testing ecosystem Big idea 3: Overlay your business understanding with your testing requirements Big idea 4: Drive testing through automation and tooling 2013-09 11 How to industrialize testing
Step 1: Industrialize your understanding of your business 1. 2. 3. You cant do a good job of testing without a good understanding of the requirements To industrialise testing you therefor have to industrialise your understanding of the business domain This means tooling and appropriate language Business process model 2013-09 12 Data model How to industrialize testing
Step 2: Industrialise the design of your testing ecosystem 1. 2. 3. 4. Industrialized testing can only be built from a structured, automated design That requires a specific, specialised language And supporting tooling Within a well specified framework Testing eco-system 2013-09 13 How to industrialize testing
..break your analysis and design of testing into manageable packages The UML Testing Profile gives the testing industry 6 domains to standardize on Test architecture: Testing meta model, business domain, testing package Test package: System Under Test, test context, test components Test configuration: Test cases, scheduler, arbiters, logs Test case: Testing activity Test data: Data pools, partitions, selectors Deployment: Nodes for SUT, Test components, Scheduler 2013-09 14 How to industrialize
Step 3: Overlay your business understanding with your testing requirements Business domain Process Overlay the testing strategy Testing domain Test strategy Process model Test cases Data Generation Generation Data model Test data 2013-09 15 How to industrialize testing
Step 4: Drive testing through automation and tooling MS Excel everywhere! MD Word testing specifications Continuous testing and integration Business and systems modelling Quality Center Because design information is structured, this interface can be automated 2013-09 16 Requirements management, test management Behaviour driven testing Testing environment virtualisation Auto testing of business rules How to industrialize testing
C: How to tool up for industrialized testing with ModelDT Tooling for planning, analysis and design Example automations with ModelDT 2013-09 17 How to industrialize testing
Tooling for planning, analysis and design You get Architectural view of testing Large scale automation Manager & Architect Risk management User Acceptance Test Test plan Test case Tester Unit test SUT Test data Programmer Test result Database User Operating model / Business process User story Project manager 2013-09 18 Test runner Test environment How to industrialize testing
Example automations with ModelDT a) Harvest and integrate existing knowledge b) Validation to the testing profile rules c) Analysis tools d) Auto generate test plans and specifications e) Auto generate code that tests your data to the requirements f) Auto generate test cases and scripts for test runners g) Synthetic test data generation h) Work in familiar Web and Excel for day to day work 2013-09 19 How to industrialize testing
a) Harvest and integrate existing knowledge Quality Center You get Synthesis De-duplication Consistency Visibility 2013-09 20 How to industrialize testing
b) Validation to the testing profile rules You get Highlights on items in error Error messages describing the break Guaranteed conformance to the UTP rules 2013-09 21 How to industrialize testing
c) Analysis tools Test components: E.g. test case Business domain – use case and data entities Coverage of business domain By testing package You get Management reports on test coverage Control reports Change impact assessments 2013-09 22 How to industrialize testing
d) Auto generate test plans and specifications You get Consistency and quality Guaranteed alignment between business domain and tests Automated specs and designs Deployment plans Test package design Automated test specifications 2013-09 23 How to industrialize testing
e) Auto generate code that tests your data to the requirements Class diagram Data format validations Schema Constraints Business rule validations You get Automated testing of data format and business rules Guaranteed alignment between requirements and tests 2013-09 24 The testing profile and its
f) Auto generate test cases and scripts for test runners Business data models Process processes Messages and signals Business processes Quality Center Junit Test scripts Test cases 2013-09 25 Test runners How to industrialize testing
g) Synthetic test data generation You get Data with 100% test coverage Guaranteed alignment of business and test data Test data fast Upload data and business rule definitions ModelDT web service Download comprehensive test data Positive test data Negative test data Business domain models 2013-09 26 How to industrialize testing
h) Work in familiar Web and Excel for day to day work RESTful web service interface Modelling interface Excel interface Database Web interface 2013-09 27 How to industrialize testing
