Main functional and regression tests for the sqlite3 WASM API.
|
|
|
|
This mini-framework works like so:
|
|
|
|
This script adds a series of test groups, each of which contains an
|
|
arbitrary number of tests, into a queue. After loading of the
|
|
sqlite3 WASM/JS module is complete, that queue is processed. If any
|
|
given test fails, the whole thing fails. This script is built such
|
|
that it can run from the main UI thread or worker thread. Test
|
|
groups and individual tests can be assigned a predicate function
|
|
which determines whether to run them or not, and this is
|
|
specifically intended to be used to toggle certain tests on or off
|
|
for the main/worker threads or the availability (or not) of
|
|
optional features such as int64 support.
|
|
|
|
Each test group defines a single state object which gets applied as
|
|
the test functions' `this` for all tests in that group. Test
|
|
functions can use that to, e.g., set up a db in an early test and
|
|
close it in a later test. Each test gets passed the sqlite3
|
|
namespace object as its only argument.
