Normalize testcase format This commit normalizes the test case format used across test262. It applies the following transformations: * Convert to YAML for frontmatter * Remove of trailing whitespace * Replace /r/n with /n except in chapters 6 and 7. * Copyright header always uses // comments * new includes attribute replaces $INCLUDE * No implicit assumptions about test environment other than $ERROR. Everything else appears in the include array. This includes "runTestCase" which is now included in a substantial number of tests. 2014-07-22 01:09:02 +02:00			`/*---`

Improve assertions comparing values to NaN (#690) The global isNaN is not precise at all, and Number.isNaN is an ES6 feature that makes it preferrable to use assert's sameValue for NaN values, as it handles it internally using the comparison. 2016-07-01 20:22:55 +02:00			`assert.sameValue(Math.acos(-1.000000000000001), NaN, "-1.000000000000001");`
