When a user goes through the Code Tour, we select a dummy `csv` database
for them to get them up and running.
Once they complete the code tour and would like to continue writing
queries, they will need to add their own database.
After they do that, we check the language of their new database and
generate a skeleton QL pack for them so that they don't need to create
these files by hand. See [1] for details.
This skeleton pack folder will be called
`codeql-custom-queries-<language>` and it comes with its own example
query: `example.ql`.
When we try to run this example query, the query gets confused about
which `dbscheme` to pick, as it sees a `qlpack.yml` file in the new
skeleton pack folder, as well as one in the existing `tutorial-lib`
folder.
So we'll need to get rid of the `tutorial-lib` folder in order to make room
for new queries to be run once the tour is complete.
This commit introduces a `handleTourDependencies` step which will
trigger a `codeql pack install` command in order to install real library
dependencies for `tutorial-queries`, since we no longer have the dummy
library in `tutorial-lib`.
We mark this query as `@kind problem`.
We'll need to change the query a bit to make it fit this type of ...
erm... kind.
This means the results view will be formatted to display the file name
next to each of the results.
We're also getting rid of any mentions of an empty block query since
that's no longer what it checks.
This will remove some instances where we're using `as unknown as T` and
replace them by a call to `mockedObject<T>()`. The `mockedObject`
function is a bit more explicit about what it does and has types which
ensure that the methods that are set on the object actually exist.
Unfortunately, we can't fully get rid of `as unknown as T` in the
`mockedObject` function. However, this construct is more localized and
does not need to be used in as many places. If we do enable an ESLint
rule to prevent the use of `as unknown as T`, I would feel comfortable
with disabling the rule for the `mockedObject` function.
This also removes the type for the `runTests` `options` argument since
it's only used in this definition and don't actually use the type
anywhere else.
