About
A quiet studio for loud coverage problems
Testing Library Digital began in Gwangju as a small circle of QA educators who were tired of treating coverage percentages as trophies. We teach application analytics for testing coverage insights so teams can explain risk with warmth and precision.
Mission
Help product and quality teams read their own data — line, branch, path, and cohort trends — without outsourcing judgment to a single green score.
Pedagogy
Every module pairs a short live demo with a worksheet you can finish in under an hour. We favor annotated screenshots from imperfect real suites over polished sample apps. Korea’s collaborative study culture shows up in peer review circles that stay open after the cohort ends.
Community
Alumni share anonymized dashboard critiques twice a month. Guests from Busan, Seoul, and remote Asia-Pacific teams rotate facilitation so the conversation never centers on one stack.
Student journey
Orient
Map your current coverage export, name the tools in play, and list the stakeholders who ask for “more coverage” without defining it.
Instrument with intent
Learn when missing data is an instrumentation gap versus a product decision. Practice tagging modules by release risk.
Narrate
Build a one-page brief that pairs charts with plain-language caveats — the skill most graduates say they reuse weekly.
Sustain
Set a dashboard hygiene cadence and join the alumni critique circle so the practice does not fade after week six.
