 174         Reviewed by Keith Miller.
 175
 176         The following tests have shown to be slow running:
 177             op_div.js
 178             op_lshift.js
 179             op_mod.js
 180             op_mul.js
 181             op_rshift.js
 182             op_sub.js
 183             op_urshift
 184
 185         These tests auto-generate permutations of values to apply to binary operations.
 186         They also test the operations with 3 permutations of value types:
 187             1. VarVar - both operands variables
 188             2. VarConst - variable operand 1, constant / literal operand 2
 189             3. ConstVar - constant / literal operand 1, variable operand 2
 190
 191         We can prevent these tests from timing out by breaking each up to only run 1 of
 192         the 3 permutations of value types.

 996
 997         Reviewed by Saam Barati.
 998
 999         Added Chakra tests.  All these tests are under Chakra/test.  This is the same layout
1000         for tests in the Chakra tree.
1001
1002         Created a ChakraCore.yaml file to be used with run-jsc-stress-tests.  This file contains
1003         the tests that are run when the original Chakra runtests.py script is run.  That script
1004         is the test driver for *nix platforms and does not attempt to run all tests or all
1005         variations of tests.  The runtest.py driver consults rlexe.xml files in each test
1006         subdirectory to determine the test to run, the options to pass to the test and how to
1007         determine pass/fail of the test.  With runtests.py as the start, tests that didn't
1008         pass directly where either skipped, with a message describing why or through
1009         adjustments to the test infrastructure, as described below, where made to pass.
1010
1011         The only modification to the test infrastrucutre are:
1012
1013          1) Added simple mapping of Chakra expected exception text to JSC expected text in
1014             test/UnitTestFramework/UnitTestFramework.js.  It would make sense to also
1015             map some JSC specific exception text to more generic text for the cases where
1016             that text contains indetifier names or other source specific strings and the
1017             Chakra equivolent exception texts are generic.
1018
1019          2) Created JSC specific expected text files where it is clear that the text work
1020             as expected on JSC but the test output is different.  Typically the differences
1021             fall into three categories, different exception output, different output from
1022             toString() of a function, slight numeric differences, and test that rely on
1023             iteration order.
1024
1025          3) Stripped the CR's from the CR-LF line terminations of the files.
1026
1027         No actual test .js files were modified.

1123         The test can fail by design, but this should be fairly rare.
1124
1125         However, when introducing, we wrap the `test()` with 1e4 to ensure the FTL compilation, and this
1126         increases the failure rate. By increasing the MAX in the test, we make the failures much more rare case.

2453         This patch moves all the JavaScript tests from Source/JavaScriptCore/tests to
2454         a new top level directory, JSTests. Having the tests in the Source directory
2455         was both confusing an inconvenient for people that just want to checkout the
2456         source code of WebKit. Since there is no other obvious place to put all the
2457         JavaScript tests a new top level directory seemed the most sensible.
2458
2459         * tests/: Deleted.
