This test has two `prettyPrint()` assertions.
The first does `prettyPrint()` no args. It passes. However, it's strange
in that two of the `found`s catch the same line:
```
IncidentToAdjacentStrategy [O] [VertexStep(OUT,vertex),
GroupStep([VertexStep(IN,vertex), GroupCountStep([VertexStep(BOTH,vertex),
CountGlobalStep, IsStep(gt(2))])],[FoldStep])
FOUND
FOUND
```
The second one does `prettyPrint(160)`. It has the same duplicate
strangeness as the first. It is also the one that consistently fails for me.
The reason being is that the `CountStrategy` line is short a character thus
doesn't match.
**Test:**
```
if (line.contains("CountStrategy") && line.contains("RangeGlobalStep(0,3)"))
```
**Input:**
```
CountStrategy [O] [VertexStep(OUT,vertex),
GroupStep([VertexStep(IN,vertex), GroupCountStep([VertexStep(BOTH,vertex),
RangeGlobalStep(0,3
```
I don't know why your `160` chars is different than my `160` chars. But why
is this being tested anyway?
