Test Lifecycle Abstraction + +A well coded test must follow a disciplined abstraction of the test +lifecycles that includes setup, configuration, test and verification. In +addition to improve test execution efficiency, the commmon aspects of +test setup and configuration shared across multiple test cases should be +done only once. Translating these high-level guidelines into the Robot +Framework one arrives to definition of a well coded RF tests for FD.io +CSIT. Anatomy of Good Tests for CSIT: + +1.

Suite Teardown - Suite post-test Configuration cleanup: uses Configuration + KWs, Verification KWs, StateReport KWs; + +## RF Keywords Functional Classification + +CSIT RF KWs are classified into the functional categories matching the test +lifecycle events described earlier. All CSIT RF L2 and L1 KWs have been grouped +into the following functional categories: + +1. Configuration; +2. Test; +3. Verification; +4. StateReport; +5. SuiteSetup; +6. TestSetup; +7. SuiteTeardown; +8. TestTeardown; + +## RF Keywords Naming Guidelines + +Readability counts: "..code is read much more often than it is written." +Hence following a good and consistent grammar practice is important when +writing Robot Framework KeyWords and Tests. All CSIT test cases +are coded using Gherkin style and include only L2 KWs references. L2 KWs are +coded using simple style and include L2 KWs, L1 KWs, and L1 python references. +To improve readability, the proposal is to use the same grammar for both +Robot Framework KW styles, and to formalize the grammar of English +sentences used for naming the Robot Framework KWs. Robot +Framework KWs names are short sentences expressing functional description of +the command. They must follow English sentence grammar in one of the following +forms: + +1. **Imperative** - verb-object(s): *"Do something"*, verb in base form. +2. **Declarative** - subject-verb-object(s): *"Subject does something"*, verb in + a third-person singular present tense form. +3. **Affirmative** - modal_verb-verb-object(s): *"Subject should be something"*, + *"Object should exist"*, verb in base form. +4. **Negative** - modal_verb-Not-verb-object(s): *"Subject should not be + something"*, *"Object should not exist"*, verb in base form. + +Passive form MUST NOT be used. However a usage of past participle as an +adjective is okay. See usage examples provided in the Coding guidelines +section below. Following sections list applicability of the above +grammar forms to different Robot Framework KW categories.

However, not all suite files +available for Jenkins jobs (or manually started bootstrap scripts) are present +in CSIT git repository. They are generated only when needed. + +## Autogen Library + +There is a code generation layer implemented as Python library called "autogen", +called by various bash scripts. + +It generates the full extent of CSIT suites, using the ones in git as templates. + +## Sources + +The generated suites (and their contents) are affected by multiple information +sources, listed below. + +### Git Suites + +The suites present in git repository act as templates for generating suites. +One of autogen design principles is that any template suite should also act +as a full suite (no placeholders). + +In practice, autogen always re-creates the template suite with exactly +the same content, it is one of checks that autogen works correctly. + +### Regenerate Script + +Not all suites present in CSIT git repository act as template for autogen. +The distinction is on per-directory level. Directories with +`regenerate_testcases.py` script usually consider all suites as templates +(unless possibly not included by the glob patten in the script). + +The script also specifies minimal frame size, indirectly, by specifying protocol +(protocol "ip4" is the default, leading to 64B frame size). + +### Constants + +Values in `Constants.py` are taken into consideration when generating suites. +The values are mostly related to different NIC models and NIC drivers. + +### Python Code + +Python code in `resources/libraries/python/autogen` contains several other +information sources. + +#### Testcase Templates + +The test case part of template suite is ignored, test case lines +are created according to text templates in `Testcase.py` file. + +#### Testcase Argument Lists + +Each testcase template has different number of "arguments", e.g. values +to put into various placeholders. Different test types need different +lists of the argument values, the lists are in `regenerate_glob` method +in `Regenerator.py` file. + +#### Iteration Over Values + +Python code detects the test type (usually by substrings of suite file name), +then iterates over different quantities based on type. +For example, only ndrpdr suite templates generate other types (mrr and soak). + +#### Hardcoded Exclusions + +Some combinations of values are known not to work, so they are excluded. +Examples: Density tests for too much CPUs; IMIX for ASTF. + +## Non-Sources + +Some information sources are available in CSIT repository, +but do not affect the suites generated by autogen. + +### Testbeds + +Overall, no information visible in topology yaml files is taken into account +by autogen. + +#### Testbed Architecture + +Historically, suite files are agnostic to testbed architecture, e.g. ICX or ALT. + +#### Testbed Size + +Historically, 2-node and 3-node suites have diferent names, and while +most of the code is common, the differences are not always simple enough. +Autogen treat 2-node and 3-node suites as independent templates. + +TRex suites are intended for a 1-node circuit of otherwise 2-node or 3-node +testbeds, so they support all 3 robot tags. +They are also detected and treated differently by autogen, +mainly because they need different testcase arguments (no CPU count). +Autogen does nothing specifically related to the fact they should run +only in testbeds/NICs with TG-TG line available. + +#### Other Topology Info + +Some bonding tests need two (parallel) links between DUTs. Autogen does not +care, as suites are agnostic. Robot tag marks the difference, but the link +presence is not explicitly checked. + +### Job specs + +Information in job spec files depend on generated suites (not the other way). +Autogen should generate more suites, as job spec is limited by time budget. +More suites should be available for manually triggered verify jobs, +so autogen covers that. + +### Bootstrap Scripts + +Historically, bootstrap scripts perform some logic, +perhaps adding exclusion options to Robot invocation +(e.g. skipping testbed+NIC combinations for tests that need parallel links). + +Once again, the logic here relies on what autogen generates, +autogen does not look into bootstrap scripts. diff --git a/docs/content/overview/csit/test_naming.md b/docs/content/overview/csit/test_naming.md new file mode 100644 index 0000000000..d7a32518e5 --- /dev/null +++ b/docs/content/overview/csit/test_naming.md @@ -0,0 +1,112 @@ +--- +title: "Test Naming" +weight: 3 +--- + +# Test Naming + +## Background + +{{< release_csit >}} follows a common structured naming convention for all +performance and system functional tests, introduced in CSIT 17.01. + +The naming should be intuitive for majority of the tests.
