The Megatest Users Manual ========================= Matt Welland <matt@kiatoa.com> v1.0, April 2012 :doctype: book [dedication] Dedication ========== Dedicated to my wife Joanna who has kindly supported my working on various projects over the years. Thanks ------ Thank you the many people I've worked over the years who have shared their knowledge and insights with me. Thanks also to the creators of the various open source projects that Megatest is built on. These include Linux, xemacs, chicken scheme, fossil and asciidoc. Without these projects something like Megatest would be difficult or impossible to do. [preface] Preface ======= This book is organised as three sub-books; getting started, writing tests and reference. Why Megatest? ~~~~~~~~~~~~~ The Megatest project was started for two reasons, the first was an immediate and pressing need for a generalized tool to manage a suite of regression tests and the second was the fact that I had written or maintained several such tools at different companies over the years and it seemed a good thing to have a single open source tool, flexible enough to meet the needs of any team doing continuous integrating and or running a complex suite of tests for release qualification. Megatest Design Philosophy ~~~~~~~~~~~~~~~~~~~~~~~~~~ Megatest is intended to provide the minimum needed resources to make writing a suite of tests and implementing continuous build for software, design engineering or process control (via owlfs for example) without being specialized for any specific problem space. Megatest in of itself does not know what constitutes a PASS or FAIL of a test. In most cases megatest is best used in conjunction with logpro or a similar tool to parse, analyze and decide on the test outcome. Megatest Architecture ~~~~~~~~~~~~~~~~~~~~~ All data to specify the tests and configure the system is stored in plain text files. All system state is stored in an sqlite3 database. Tests are launched using the launching system available for the distributed compute platform in use. A template script is provided which can launch jobs on local and remote Linux hosts. Currently megatest uses the network filesystem to call home to your master sqlite3 database. include::getting_started.txt[] include::writing_tests.txt[] include::reference.txt[] Controlled waiver propagation ============================= If test is FAIL and previous test in run with same MT_TARGET is WAIVED then apply the following rules from the testconfig: If a waiver check is specified in the testconfig apply the check and if it passes then set this FAIL to WAIVED Waiver check has two parts, 1) a list of waiver, rulename, filepatterns and 2) the rulename script spec (note that "diff" and "logpro" are predefined) ========================================================= ###### EXAMPLE FROM testconfig ######### # matching file(s) will be diff'd with previous run and logpro applied # if PASS or WARN result from logpro then WAIVER state is set # [waivers] # logpro_file rulename input_glob waiver_1 logpro lookittmp.log [waiver_rules] # This builtin rule is the default if there is no <waivername>.logpro file # diff diff %file1% %file2% # This builtin rule is applied if a <waivername>.logpro file exists # logpro diff %file1% %file2% | logpro %waivername%.logpro %waivername%.html ========================================================= [appendix] Example Appendix ================ One or more optional appendixes go here at section level zero. Appendix Sub-section ~~~~~~~~~~~~~~~~~~~ NOTE: Preface and appendix subsections start out of sequence at level 2 (level 1 is skipped). This only applies to multi-part book documents. [bibliography] Example Bibliography ==================== The bibliography list is a style of AsciiDoc bulleted list. [bibliography] - [[[taoup]]] Eric Steven Raymond. 'The Art of Unix Programming'. Addison-Wesley. ISBN 0-13-142901-9. - [[[walsh-muellner]]] Norman Walsh & Leonard Muellner. 'DocBook - The Definitive Guide'. O'Reilly & Associates. 1999. ISBN 1-56592-580-7. [glossary] Example Glossary ================ Glossaries are optional. Glossaries entries are an example of a style of AsciiDoc labeled lists. [glossary] A glossary term:: The corresponding (indented) definition. A second glossary term:: The corresponding (indented) definition. [colophon] Example Colophon ================ Text at the end of a book describing facts about its production.
