+**Dunder methods**
+
+Double-underscore methods, or "dunder" methods, are special methods defined in a class that are invoked implicitly. Like the name suggests, they are prefixed and suffixed with dunders. You've probably already seen some, such as the `__init__` dunder method, also known as the "constructor" of a class, which is implicitly invoked when you instantiate an instance of a class.
+
+When you create a new class, there will be default dunder methods inherited from the `object` class. However, we can override them by redefining these methods within the new class. For example, the default `__init__` method from `object` doesn't take any arguments, so we almost always override that to fit our needs.
+
+Other common dunder methods to override are `__str__` and `__repr__`. `__repr__` is the developer-friendly string representation of an object - usually the syntax to recreate it - and is implicitly called on arguments passed into the `repr` function. `__str__` is the user-friendly string representation of an object, and is called by the `str` function. Note here that, if not overriden, the default `__str__` invokes `__repr__` as a fallback.
+
+```py
+class Foo:
+    def __init__(self, value):  # constructor
+        self.value = value
+    def __str__(self):
+        return f"This is a Foo object, with a value of {self.value}!"  # string representation
+    def __repr__(self):
+        return f"Foo({self.value!r})"  # way to recreate this object
+
+
+bar = Foo(5)
+
+# print also implicitly calls __str__
+print(bar)  # Output: This is a Foo object, with a value of 5!
+
+# dev-friendly representation
+print(repr(bar))  # Output: Foo(5)
+```
+
+Another example: did you know that when you use the `<left operand> + <right operand>` syntax, you're implicitly calling `<left operand>.__add__(<right operand>)`? The same applies to other operators, and you can look at the [`operator` built-in module documentation](https://docs.python.org/3/library/operator.html) for more information!

+To ensure the results you obtain on your personal machine are comparable to those generated in the CI, please make sure to run your tests with the virtual environment defined by our [Poetry Project](/pyproject.toml). To run your tests with `poetry`, we've provided the following "script" shortcuts:
 
-- `poetry run task test` will run `unittest` with `coverage.py`
+- `poetry run task test-nocov` will run `pytest`.
+- `poetry run task test` will run `pytest` with `pytest-cov`.
 - `poetry run task test path/to/test.py` will run a specific test.
 - `poetry run task report` will generate a coverage report of the tests you've run with `poetry run task test`. If you append the `-m` flag to this command, the report will include the lines and branches not covered by tests in addition to the test coverage report.
 
 If you want a coverage report, make sure to run the tests with `poetry run task test` *first*.
 
+## Running tests
+There are multiple ways to run the tests, which one you use will be determined by your goal, and stage in development.
+
+When actively developing, you'll most likely be working on one portion of the codebase, and as a result, won't need to run the entire test suite.
+To run just one file, and save time, you can use the following command:
+```shell
+poetry run task test-nocov <path/to/file.py>
+```
+
+For example:
+```shell
+poetry run task test-nocov tests/bot/exts/test_cogs.py
+```
+will run the test suite in the `test_cogs` file.
+
+If you'd like to collect coverage as well, you can append `--cov` to the command above.
+
+
+If you're done and are preparing to commit and push your code, it's a good idea to run the entire test suite as a sanity check:
+```shell
+poetry run task test
+```
+
 ## Writing tests
 
 Since consistency is an important consideration for collaborative projects, we have written some guidelines on writing tests for the bot. In addition to these guidelines, it's a good idea to look at the existing code base for examples (e.g., [`test_converters.py`](/tests/bot/test_converters.py)).
