我在代码中使用这样的rackunit
(run-tests (test-suite "suite-name"
(test-case "case name"
...
))
我正在努力练习TDD。当断言失败时，我可以看到哪个断言失败了。但不幸的是，在出现错误的情况下，rackunit只向我显示遇到的错误和失败的测试用例名称。
如果我正常执行代码，我会看到带有行号的堆栈跟踪。我怎样才能让球拍显示这些信息？
使用错误跟踪。
例如，以下程序
#lang racket/base
(require rackunit
rackunit/text-ui)
(define suite
(test-suite "suite-name"
(test-case "case name"
(check-equal? (1) 3))))
(run-tests suite)
生产：
--------------------
suite-name > case name
ERROR
application: not a procedure;
expected a procedure that can be applied to arguments
given: 1
arguments...: [none]
--------------------
0 success(es) 0 failure(s) 1 error(s) 1 test(s) run
1
当您使用racket test.rkt运行时。
但如果我们用racket -l errortrace -t test.rkt运行它，那么它会产生：
--------------------
suite-name > case name
application: not a procedure;
expected a procedure that can be applied to arguments
given: 1
arguments...: [none]
