Functions

func Condition added in v0.3.0

func Condition(cond string) (bool, error)

Condition adds support for CUE-specific testscript conditions within testscript scripts. Supported conditions include:

golang.org/issue/N - evaluates to true unless CUE_NON_ISSUES is set to a regexp that matches the condition, i.e. golang.org/issue/N in this case

cuelang.org/issue/N - evaluates to true unless CUE_NON_ISSUES is set to a regexp that matches the condition, i.e. cuelang.org/issue/N in this case

func IssueSkip added in v0.3.0

func IssueSkip(t *testing.T, s string)

IssueSkip causes the test t to be skipped unless the issue identified by s is deemed to be a non-issue by CUE_NON_ISSUES.

func Run

func Run[TC any](t *testing.T, table []TC, fn func(t *T, tc *TC))

Run creates a new table-driven test using the CUE testing defaults.

TODO: move this wrapper out to cuetdtest. Users should either use the full version of tdtest directly, or use the cuetdtest wrapper.

func (*Chunker) Find

func (c *Chunker) Find(key string) bool

Next finds the first occurrence from the current scan position of beg, records the segment from that position until the first occurrence of end and then updates the current position. It reports whether a segment enclosed by beg and end can be found.
