|:---------|:--------------|
| `number` | `2` |
Depth of object traversal. If object depth is greater than `maxDepth`, compound object (IOW, `Array` or `object`) will be pruned with `#` like `["foo",#Array#,#Object#]`.
#### options.lineSeparator
| type | default value |
|:---------|:--------------|
| `string` | `"\n"` |
Line separator in power assert output.
#### options.anonymous

Function to create diff string between two strings.
#### options.lineDiffThreshold
| type | default value |
|:---------|:--------------|
| `number` | `5` |
Threshold to show diff at character level or line level. If number of lines in target string is greater than `lineDiffThreshold`, then line diff mode will be used to show diff output.
