The 80/20 rule for software test coverage

🔧 Legacy code: rewrite or refactor?

Key factors:
- Security risks?
- Framework support?
- Team understanding of features/usage?
- Risk tolerance?
- Team's ability to maintain existing vs new system?

Pro tip: There is no magic answer. It's always situational.

We've seen incremental refactors that unlocked business value and speed super quick, and also glacially slow refactors.

We've seen big bang rewrites turn into snail's-pace, expensive disasters, and also super successful iterations.

Last week Double Agents Anya Iverova, Cathy Colliver, and Christine McCallum-Randalls attended All Things AI. Here's an unclassified field report from the sessions they attended. https://link.testdouble.com/fbce39

Remote work reality check: Scheduled meetings build efficiency. Unstructured time builds trust.

Our consultant Tyler Sloane discovered that "coffee and code" sessions - open video calls with no agenda - create the serendipitous connections that make remote teams actually work.

We spent fifty years building software abstractions for human cognition. Agentic coding starts pulling in the other direction. @DocOnDev says we may need to renegotiate the abstractions.

Slow investigations, inconclusive root causes, and recurring bugs are observability problems. But fixing them isn't primarily a tooling problem.
Gabriel Côté-Carrier spent months turning observability from a team pain point into a genuine advantage. The technical work was only half of it.

"In a world where every meeting has an agenda, sometimes the most valuable thing we can offer is purposeless presence."

Tyler Sloane's take on building real connections in remote work is worth the read: https://link.testdouble.com/e704e9

Python devs, is this familiar: Your team writes beautiful snake_case code, but every external API wants camelCase.

You could:
- Pollute your codebase with non-Pythonic naming
- Write manual conversion layers
- Live with the friction

Or you could use Pydantic's field aliases to solve this once and for all.

New guide: How to handle non-Pythonic naming conventions seamlessly 👇

AI can pattern-match. It can’t always tell you when the pattern doesn't apply ... because it doesn’t always have (and sometimes loses) context.

Senior engineers and product managers who've shipped real products, untangled real legacy systems, and made real calls under pressure bring something different to the table.

Test Double's free office hours give you access to exactly that. No strings attached.

We can help you discern when patterns actually apply.
