also move the `walkTree` call to above the "missed" type-checking as it needs to come first importantly, `buildEnd` also occurs before output generation, so this ensures that type-checking still occurs even if `bundle.generate()` is not called no longer need `_ongenerate` as that should be in `buildEnd`, and no longer need `_onwrite` as it is the only thing called in `generateBundle`, so just combine them

so now that it does, we can use it to simplify some logic per ezolenko, the whole generateRound etc stuff was a workaround because the buildEnd hook actually _didn't exist_ before * wip: fuse _ongenerate functionality into buildEnd, _onwrite into generateBundle that can result in a file being type-checked but not added to checkedFiles because printing diagnostics can bail if the category was error * move checkedFiles.add to the beginning of typecheckFile and because `declarations` dict is empty when `declaration: false`, so can't check against that since `parsedConfig.fileNames` could include files that were already checked during the `transform` hook * add new checkedFiles Set to not duplicate type-checking if `declaration: false` not the most common use-case for rpt2, but it is one remove the check against the `declarations` dict as one can type-check without outputting declarations and this means it's only called once per build, vs. `buildEnd` is a more correct place for it, since this does not generate any output files * move misssed type-checking to `buildEnd` hook, remove declarations check _already_ generate declarations for those files)) That the user wanted type-checking and declarations for (as we these would basically be independent TS files not part of the bundle _not_ type-only) that are in the `include` and weren't

(_technically_ speaking, there could be full TS files we do the same process for generating declarations for "missed"įiles right now in `_onwrite`, so basically do the same thing but Using glob patterns in `include`) - this is just a workaround, Particular if one is using `tsconfig` `files` (or in general _not_ note that this will not catch _all_ type-only imports, in in `parsedConfig.fileNames`) are also type-checked so, as a workaround, make sure that all files in the `tsconfig`

type-only files never get processed by Rollup as their imports areĮlided/removed by TS in the resulting compiled JS file * fix: type-check `include`d files missed by transform (type-only files) Wherever I was mocking modules or making spyOn. We can check what arguments were passed to a function using, or by accessing the call directly using spy.lastCall or spy.getCall().It('1. To make it easier to understand what we’re talking about, below is a simple function to illustrate the examples.

In this article, we’ll show you the differences between spies, stubs and mocks, when and how to use them, and give you a set of best practices to help you avoid common pitfalls. They also have some gotchas, so you need to know what you’re doing to avoid problems. You get a lot of functionality in the form of what it calls spies, stubs and mocks, but it can be difficult to choose when to use what. However, getting started with Sinon might be tricky. We can make use of its features to simplify the above cases into just a few lines of code. Thankfully, we can use Sinon.js to avoid all the hassles involved. With databases, you need to have a testing database set up with data for your tests.Īll of this means that writing and running tests is harder, because you need to do extra work to prepare and set up an environment where your tests can succeed. For example, if you use Ajax or networking, you need to have a server, which responds to your requests.

Testing code with Ajax, networking, timeouts, databases, or other dependencies can be difficult.
