 ## Standards
 
 Contributions to Open MCT are expected to meet the following standards.
@@ -122,97 +131,104 @@ changes.
 
 ### Code Standards
 
-JavaScript sources in Open MCT must satisfy JSLint under its default
-settings. This is verified by the command line build.
+JavaScript sources in Open MCT must satisfy the ESLint rules defined in 
+this repository. This is verified by the command line build.
 
 #### Code Guidelines
 
-JavaScript sources in Open MCT should:
-
-* Use four spaces for indentation. Tabs should not be used.
-* Include JSDoc for any exposed API (e.g. public methods, constructors).
-* Include non-JSDoc comments as-needed for explaining private variables,
-  methods, or algorithms when they are non-obvious.
-* Define one public class per script, expressed as a constructor function
-  returned from an AMD-style module.
-* Follow “Java-like” naming conventions. These includes:
-  * Classes should use camel case, first letter capitalized
-    (e.g. SomeClassName).
-  * Methods, variables, fields, and function names should use camel case,
-    first letter lower-case (e.g. someVariableName).
-  * Constants (variables or fields which are meant to be declared and 
-    initialized statically, and never changed) should use only capital 
-    letters, with underscores between words (e.g. SOME_CONSTANT).
-  * File names should be the name of the exported class, plus a .js extension
-    (e.g. SomeClassName.js).
-* Avoid anonymous functions, except when functions are short (a few lines)
-  and/or their inclusion makes sense within the flow of the code
-  (e.g. as arguments to a forEach call).
-* Avoid deep nesting (especially of functions), except where necessary
-  (e.g. due to closure scope).
-* End with a single new-line character.
-* Expose public methods by declaring them on the class's prototype.
-* Within a given function's scope, do not mix declarations and imperative
-  code, and  present these in the following order:
-  * First, variable declarations and initialization.
-  * Second, function declarations.
-  * Third, imperative statements.
-  * Finally, the returned value.
+The following guidelines are provided for anyone contributing source code to the Open MCT project:
 
+1. Write clean code. Here’s a good summary - https://github.com/ryanmcdermott/clean-code-javascript.
+1. Include JSDoc for any exposed API (e.g. public methods, classes).
+1. Include non-JSDoc comments as-needed for explaining private variables,
+   methods, or algorithms when they are non-obvious. Otherwise code 
+   should be self-documenting.
+1. Classes and Vue components should use camel case, first letter capitalized
+   (e.g. SomeClassName).
+1. Methods, variables, fields, events, and function names should use camelCase,
+   first letter lower-case (e.g. someVariableName).
+1. Source files that export functions should use camelCase, first letter lower-case (eg. testTools.js)
+1. Constants (variables or fields which are meant to be declared and 
+   initialized statically, and never changed) should use only capital 
+   letters, with underscores between words (e.g. SOME_CONSTANT). They should always be declared as `const`s
+1. File names should be the name of the exported class, plus a .js extension
+   (e.g. SomeClassName.js).
+1. Avoid anonymous functions, except when functions are short (one or two lines)
+   and their inclusion makes sense within the flow of the code
+   (e.g. as arguments to a forEach call). Anonymous functions should always be arrow functions.
+1. Named functions are preferred over functions assigned to variables.
+   eg.
+   ```JavaScript
+   function renameObject(object, newName) {
+       Object.name = newName;
+   }
+   ```
+   is preferable to
+   ```JavaScript
+   const rename = (object, newName) => {
+       Object.name = newName;
+   }
+   ```
+1. Avoid deep nesting (especially of functions), except where necessary
+   (e.g. due to closure scope).
+1. End with a single new-line character.
+1. Always use ES6 `Class`es and inheritence rather than the pre-ES6 prototypal 
+   pattern.
+1. Within a given function's scope, do not mix declarations and imperative
+   code, and  present these in the following order:
+   * First, variable declarations and initialization.
+   * Secondly, imperative statements.
+   * Finally, the returned value. A single return statement at the end of the function should be used, except where an early return would improve code clarity.
+1. Avoid the use of "magic" values.
+   eg.
+   ```JavaScript
+   Const UNAUTHORIZED = 401
+   if (responseCode === UNAUTHORIZED)
+   ```
+   is preferable to
+   ```JavaScript
+   if (responseCode === 401)
+   ```
+1. Use the ternary operator only for simple cases such as variable assignment. Nested ternaries should be avoided in all cases.
+1. Test specs should reside alongside the source code they test, not in a separate directory.
+1. Organize code by feature, not by type.
+   eg.
+   ```
+   - telemetryTable
+       - row
+           TableRow.js
+           TableRowCollection.js
+           TableRow.vue
+       - column
+           TableColumn.js
+           TableColumn.vue
+       plugin.js
+       pluginSpec.js
+   ```
+   is preferable to
+   ```
+   - telemetryTable
+       - components
+           TableRow.vue
+           TableColumn.vue
+       - collections
+           TableRowCollection.js
+       TableColumn.js
+       TableRow.js
+       plugin.js
+       pluginSpec.js
+   ```

-During automated testing, code coverage metrics will be reported. Line
-coverage must remain at or above 80%.
+#### Guidelines
+* 100% statement coverage is achievable and desirable.
+* Do blackbox testing. Test external behaviors, not internal details. Write tests that describe what your plugin is supposed to do. How it does this doesn't matter, so don't test it.
+* Unit test specs for plugins should be defined at the plugin level. Start with one test spec per plugin named pluginSpec.js, and as this test spec grows too big, break it up into multiple test specs that logically group related tests.
+* Unit tests for API or for utility functions and classes may be defined at a per-source file level.
+* Wherever possible only use and mock public API, builtin functions, and UI in your test specs. Do not directly invoke any private functions. ie. only call or mock functions and objects exposed by openmct.* (eg. openmct.telemetry, openmct.objectView, etc.), and builtin browser functions (fetch, requestAnimationFrame, setTimeout, etc.).
+* Where builtin functions have been mocked, be sure to clear them between tests.
+* Test at an appropriate level of isolation. Eg. 
+    * If you’re testing a view, you do not need to test the whole application UI, you can just fetch the view provider using the public API and render the view into an element that you have created. 
+    * You do not need to test that the view switcher works, there should be separate tests for that. 
+    * You do not need to test that telemetry providers work, you can mock openmct.telemetry.request() to feed test data to the view.
+    * Use your best judgement when deciding on appropriate scope.
+* Automated tests for plugins should start by actually installing the plugin being tested, and then test that installing the plugin adds the desired features and behavior to Open MCT, observing the above rules.
+* All variables used in a test spec, including any instances of the Open MCT API should be declared inside of an appropriate block scope (not at the root level of the source file), and should be initialized in the relevant beforeEach block. `beforeEach` is preferable to `beforeAll` to avoid leaking of state between tests.
+* A `afterEach` or `afterAll` should be used to do any clean up necessary to prevent leakage of state between test specs. This can happen when functions on `window` are wrapped, or when the URL is changed. [A convenience function](https://github.com/nasa/openmct/blob/master/src/utils/testing.js#L59) is provided for resetting the URL and clearing builtin spies between tests.
+* If writing unit tests for legacy Angular code be sure to follow [best practices in order to avoid memory leaks](https://www.thecodecampus.de/blog/avoid-memory-leaks-angularjs-unit-tests/).

+### Testathons
+Testathons can be used as a means of performing per-sprint and per-release testing. 
+
+#### Timing
+For per-sprint testing, a testathon is typically performed at the beginning of the third week of a sprint, and again later that week to verify any fixes. For per-release testing, a testathon is typically performed prior to any formal testing processes that are applicable to that release.
+
+#### Process
+
+1. Prior to the scheduled testathon, a list will be compiled of all issues that are closed and unverified.
+2. For each issue, testers should review the associated PR for testing instructions. See the contributing guide for instructions on [pull requests](https://github.com/nasa/openmct/blob/master/CONTRIBUTING.md#merging).
+3. As each issue is verified via testing, any team members testing it should leave a comment on that issue indicating that it has been verified fixed.
+4. If a bug is found that relates to an issue being tested, notes should be included on the associated issue, and the issue should be reopened. Bug notes should include reproduction steps.
+5. For any bugs that are not obviously related to any of the issues under test, a new issue should be created with details about the bug, including reproduction steps. If unsure about whether a bug relates to an issue being tested, just create a new issue.
+6. At the end of the testathon, triage will take place, where all tested issues will be reviewed.
+7. If verified fixed, an issue will remain closed, and will have the “unverified” label removed.
+8. For any bugs found, a severity will be assigned.
+9. A second testathon will be scheduled for later in the week that will aim to address all issues identified as blockers, as well as any other issues scoped by the team during triage.
+10. Any issues that were not tested will remain "unverified" and will be picked up in the next testathon.
