33 // are generated at the beginning of the test and do not change.
34 // * a.js
35 // print("A: " + arguments)
36 // * b.js
37 // #!<path_to_jjs> -lalelu -- ignore
38 // print("B: " + arguments)
39 //
40 // The third file, shebang.js, is generated differently for each particular
41 // test case, containing different shebang lines and one statement:
42 // * shebang.js
43 // #!<path_to_jjs> <shebang_line>
44 // print("S: " + arguments)
45 //
46 // The path_to_jjs is extracted from the environment based on JAVA_HOME, so the
47 // latter must be set properly.
48 //
49 // Each shebang.js is run four times, in all possible combinations of values
50 // from the following two axes:
51 // * without passing any arguments, and passing the arguments 'a.js' and
52 // '"hello world"' (the latter being a quoted string);
53 // * run via jjs, and via direct shell execution (using shebang).
