+With the basic outline of our pattern ready, now would be a good time
+to test it to see how well it adapts to different measurements,
+and the range of options we provided.

+
+###### No more grading
+
+FreeSewing patterns are _made-to-measure_, which means that you don't need to
+grade your pattern to provide a range of sizes. You should sample your pattern
+for different measurements and options to see how well it adapts.
+
+</Tip>
+
+If testing your pattern sounds like a lot of work, you're in luck. FreeSewing can do it
+for you. Click the **Test Design** link in the sidebar under the **View** title.
+
+You have a number of ways to test your pattern:
+
+- Test design options
+- Test measurements
+- Test models
+
+The [API docs on sampling](/reference/api/pattern/sample) have all the details
+on how this works, but for now we'll just look at the end result of each of
+these.
+
+## Testing pattern options
+
+We used percentage options, which can vary between their minimum and maximum
+value.  For these tests, FreeSewing will divide that range into 10 steps and
+draft your pattern for each step.
+
+Click on any of the options we've added to our pattern, and your bib will be
+drawn with that option sampled.
+
+### lengthRatio
+
+The `lengthRatio` option controls the length of our bib. Testing it confirms
+that it only influences the length:
+
+![This is what it should look like when you test the `lengthRatio`
+option](test-option-lengthratio.png)
+

+
+### neckRatio
+
+The `neckRatio` option will determine the size of the neck opening.  For a the
+same `head` measurement, varying this option should result in bibs with
+increasingly larger neck opening.
+
+Testing it confirms this. We can also see that as the neck opening gets
+smaller, we will rotate the straps further out of the way to avoid overlap:
+
+![This is what it should look like when you test the `neckRatio`
+option](test-option-neckratio.png)
+
+<Fixme compact>Update screenshot for v3</Fixme>
+
+### widthRatio
+
+The `widthRatio` option will determine the width of our bib.  For the same
+`head` measurement, varying this option should result in increasingly wider
+bibs.
+
+If we test it, we can see that it works as intended. But there's one thing that
+perhaps requires your attention. Making the bib wider shortens the length from
+the bottom of the neck opening to the bottom of the bib. Thereby making the
+bib shorter when it's worn.
+
+![This is what it should look like when you test the `widthRatio`
+option](test-option-widthratio.png)
+
+<Fixme compact>Update screenshot for v3</Fixme>
+
+<Note>
+
+Even if the _total length_ of the bib stays the same, the _useable length_
+shortens when the bib is made wider. Users will not expect this, so it's
+something that we should fix in our pattern.
+
+Adjusting the pattern to make the `widthRatio` not influence the _useable
+length_ of the bib is not covered in this tutorial. It is left _as an exercise
+to the reader_.
+
+</Note>
+
+## Testing measurements
+
+Testing a measurement will vary that measurement 10% up or down while leaving
+everything else the same.  This gives you the option to determine how any given
+measurement is influencing the pattern.
+
+For our bib, we only use one measurement, so it influences the entire pattern.
+

+
+## Testing models
+
+Whereas testing a measurement will only vary one individual measurement,
+testing models will draft your pattern for different sets of measurements, which
+we refer to as _models_.
+
+On the surface, the result below is the same as our measurement test. But that
+is because our bib only uses one measurement. So testing that one measurement
+ends up being the same as testing a complete set of measurements.
+
+But most patterns use multiple measurements, and you'll find this test gives
+you insight into how your pattern will adapt to differently sized bodies.

+
+## The antperson test
+
+A special case of model testing is the so-called _antperson test_.  It drafts
+your pattern with a set of _typical_ measurements , and then drafts it again
+with measurements that are 1/10th of those _typical_ measurements.
+
+It is named after [the cartoon
+character](https://en.wikipedia.org/wiki/Ant-Man_\(film\)) who can shrink, yet
+somehow his suit still fits.
+
+The purpose of the antperson test is to bring out areas in your pattern where
+you made assumptions that will not properly scale.  Many drafting books will
+tell you to _add 3 cm there_ or _measure 2 inch to the right_. Those
+instructions don't scale, and you should avoid them.
+
+The best patterns will pass the antperson test with 2 patterns exactly the
+same, where one will simply be 1/10th the scale of the other.

+
+When you're happy with how your pattern passes these tests, it's time to
+complete our design.
