mmo-js-tests

The javascript test suite, run from the page.

<mmo-js-tests filter="" auto></mmo-js-tests>

Extends: CustomShadowElement

It is a face for `tests/js-node/run.js`, reached through `MMO\client\controllers\TestsController`: the picker is the runner's `--list`, the Run button is its `--json` mode, and what is drawn below is the report it printed. No test runs in this page -- they run in node, on the server, against the sources rather than against the bundle this page is painted by, which is the whole point: a test that passed here because the page happened to have the right globals would be worthless. The element draws a hint and nothing else when the application did not register that controller, so a page can carry it unconditionally. ### Reading a result A suite is a file, a row is one `test*` method. A failure shows the assertion's own message -- expected against actual, as the assertion wrote it -- and, when it was a crash rather than an assertion, the stack. Anything a test printed on the console is captured by the runner and hangs under the test that printed it, rather than being interleaved into one stream nobody can attribute. A file is collapsed to one line -- its name, its counts, its time -- and opens on a click. What failed opens on its own, and stays open when it is re-run, so the report is a short list that grows only where someone asked it to. **Expand** opens or closes every file at once, and **Failures** narrows the list to what failed, files included: between them, 356 tests read as 17 rows. ```html <mmo-js-tests></mmo-js-tests>  <mmo-js-tests filter="MMO.tests.core.Map" auto="false"></mmo-js-tests> ```

Methods9

constructor()

mmo-js-tests.jhs:129

constructor()

init()

mmo-js-tests.jhs:135

init()

message(state, message)

mmo-js-tests.jhs:157

Set the strip's state and its message.

message(state, message)

state	`string`	- '', 'busy', 'ok' or 'error'; it is also the css class
message	`string`

request(path, method, body)

mmo-js-tests.jhs:173

Call one of the controller's routes.

request(path, method = 'GET', body = null)

A failing *test* is a 200 with a report; only the runner failing is an error status, and the server's own message is what explains it (a missing node, a missing jsdom), so it is read out of the body rather than replaced by the status text.

path	`string`	- `jsTests` or `jsTestsRun`
method = 'GET'	`string`
body = null	`?object`
returns	`Promise`	the route's payload

load()

mmo-js-tests.jhs:194

Read the namespaces the suite holds, and fill the picker.

load()

returns Promise

run(namespace)

mmo-js-tests.jhs:219

Run the suite, or the one namespace given.

run(namespace = null)

namespace = null	`?string`	- what to run; the picker's own value when omitted
returns	`Promise`

setReport(report)

mmo-js-tests.jhs:248

Draw a report.

setReport(report)

Every value the markup binds is computed here rather than in the template: a `status` class per suite and per test, and the summary line. The report itself is never mutated.

report	`object`	- what `run.js --json` printed
returns	`void`

toggleAll()

mmo-js-tests.jhs:301

Open or close every file at once.

toggleAll()

The state is written into the model rather than onto the nodes, so it survives the `only failures` filter and anything else that re-reads the view.

returns void

toggleFailures()

mmo-js-tests.jhs:316

Show every test, or only what failed. The filtering is a class on the host, so it costs no re-render: a report of 356 rows is drawn once and narrowed by css.

toggleFailures()

returns void
