Notes on test coverage - jml :: Jonathan Lange
every new project should have 100% test coverage
every existing project should have a ratchet that enforces increasing coverage
“100% coverage” means that every line is either:
covered by the test suite
or has some markup in code saying that it is explicitly not covered, and why that’s the case
these should be enforced in CI

Using a Jenkinsfile
Creating a Jenkinsfile, which is checked into source control [1], provides a number of immediate benefits:

Code review/iteration on the Pipeline

Audit trail for the Pipeline

Single source of truth [2] for the Pipeline, which can be viewed and edited by multiple members of the project.

Packaging a python library | ionel's codelog

Put code in src.
Use tox and detox.
Test both with coverage measurements and without.
Use a generator script for tox.ini and .travis.ini.
Run the tests in Travis with tox to keep things consistent with local testing.

Too complicated? Just use a python package template.

Gerald Weinberg's Secrets of Writing and Consulting: Fuzz Testing and Fuzz History
The "trash deck technique" (using decks of punch cards salvaged from the trash as test input) was universal among programmers in the 1950s.

Open Jail - The Jailer Project Web Site
Jailer is a tool for database subsetting, schema and data browsing. It exports consistent, referentially intact row-sets from relational databases. It removes obsolete data without violating integrity. It is DBMS agnostic (by using JDBC), platform independent, and generates DbUnit datasets, hierarchically structured XML, and topologically sorted SQL-DML.

Evaluating Fuzz Testing - 1808.09700.pdf
Most empirical analyses of fuzz-testing have bad experimental design and/or statistical analysis.

Linux is not about choice [was Re: Fedora too cutting edge?]
The complaints up-thread about juju and pulse are entirely valid, but the solution is not to try to deliver two things at once. If you try to deliver both at once you have to also deliver a way of switching between the two. Now you have three moving parts instead of one, which means the failure rate has gone up by a factor of _six_ (three parts, and three interactions).

Just a Whole Bunch of Different Tests • Hillel Wayne
I’ve been working on a bunch of longform obligation pieces and while they’re a lot of fun, they’re also steadily driving me insane. So I took a day off to write about all of the kinds of automated testing I know about. I’m defining tests here to be “an independent verification program that, as part of verification, executes the code we want to verify.” This means types are not tests, as they don’t involve execution of the code, and contracts are not tests, because they’re not execute...

To Do Damage? (TDD) – Medium
Types qualify, document and codify the concepts chosen by the
developers in solving a problem. Testing at various levels can
certainly do some of that to different degrees but fundamentally is
about verifying that the code solves the problem in hand and has
little to say about the qualities of the concepts chosen.

Grenade - OpenStack
Grenade is a test harness to exercise the OpenStack upgrade process between releases. It uses DevStack to perform the initial OpenStack install and then walks through upgrading each enabled project.

Mistaeks I Hav Made: Two Hypotheses per Test
1. System Hypothesis: the code performs the externally visible behaviour verified by the test.
2. Model Hypothesis: the domain model encompasses the structures required to implement that behaviour.
