Since there are now multiple files requiring a mocha environment, I'd rather
create a test/.eslintrc.json file (similar to qunit/.eslintrc.json) and remove
those inline configuration comments.

Done.

+"use strict";

+const webdriver = require("selenium-webdriver");
+const {By, until} = webdriver;

Nit: Unused imports? I don't see webdriver, By and until being used below.

[tlucas, 2018/09/01 11:54:24]

You are right about "webdriver",however "By" and "until" are used in e.g. line
30:

     this.driver.wait(until.elementLocated(By.id("qunit-testresult")))
                      ^                    ^

Done.

+const assert = require("assert");
+
+it("qunit", function()
+{
+  return this.driver.navigate().to(this.origin + "/qunit/index.html").then(() =>
+    // Wait for qunit-results to be present
+    this.driver.wait(until.elementLocated(By.id("qunit-testresult")))
+  ).then(() =>
+    // Wait for tests to finish
+    this.driver.wait(() =>
+      this.driver.findElement(By.id("qunit-testresult"))
+        .getAttribute("innerHTML").then(data =>
+           data.includes("Tests completed")))
+  ).then(() => Promise.all([[true, ".pass"], [false, ".fail"]].map(
+    ([success, sel]) => this.driver.findElements(
+      By.css(`#qunit-tests ${sel} .test-name`)
+    ).then(elements => Promise.all(elements.map(elem =>
+      elem.getAttribute("textContent").then(data => assert.ok(success, data))
+    )))
+  )));
+});
