Matrix Testing for Examples

[ryanleecode]

For virtual.eg.ts we currently test it as is without specifying the state flag. How might we approach testing no state flag and with state flag to get full coverage. Same question for other examples with flags.

This is important if we plan on adding additional flags i.e. use-stash and want full test coverage

const args = parse(Deno.args, { string: ["state"], boolean: ["use-stash"] })

Perhaps this would be best as an issue on https://github.com/paritytech/egts?

Agreed: we can specify variants / alternative inputs in the frontmatter/module-level docs.

/**
 * // ...
 * @alt flags --state <somestatevaluehere>
 */

In this case, we specify an alternative run with the flags following flags.

We may also want to prefix egts-specific frontmatter fields (including @skip_test).

/**
 * // ...
 * @egts:alt flags --state <somestatevaluehere>
 */
