// 1) The base checkout directory of tape might change. Because stack traces
|
||
|
|
// include absolute paths, the stack traces will change depending on the
|
||
|
|
// checkout path. We handle this by replacing the base test directory with a
|
||
|
|
// placeholder $TEST variable and the package root with a placeholder
|
||
|
|
// $TAPE variable.
|
||
|
|
// 2) Line positions within the file might change. We handle this by replacing
|
||
|
|
// line and column markers with placeholder $LINE and $COL "variables"
|
||
|
|
// a) node 0.8 does not provide nested eval line numbers, so we remove them
|
||
|
|
// 3) Stacks themselves change frequently with refactoring. We've even run into
|
||
|
|
// issues with node library refactorings "breaking" stack traces. Most of
|
||
|
|
// these changes are irrelevant to the tests themselves. To counter this, we
|

|
|
// strip out all stack frames that aren't directly under our test directory,

|
|
// and replace them with placeholders.
