Deno is in v0.40.0 at the time I made this presentation. Some presented patterns may evolve in further releases. Purpose is to present the opinionated choices deno made in its architecture. 3
first IT job interview 4 For the algorithm test we should begin with Fibonacci. Do you know it ? Yes, I studied it in highschool Ok great ! Could you begin with a unit test ? I never did a unit test of my life sorry ! but maybe can you help me ?
years later 8 deno test Hey Lilian ! Deno looks so great but how do you test ? Try yourself and make a presentation ! Ok but what are the patterns ? What do you write ? Ok then...
11 • No watch mode out of the box • Specs are executed sequentially (no parallelism) • Coverage is missing • Files must respect pattern (can be tricked with Deno.runTests())
25 • deno dev experience is great (thanks to axetroy extension for vs code) • testing std & cli are not production ready at all • I hope the bench API will be kept
