A tinytest
object. A tinytest object is a
logical
with attributes holding information about the
test that was run
[R object or expression]
Outcome or expression under scrutiny.
[R object or expression]
Expected outcome
[numeric]
Test equality to machine rounding. Passed
to all.equal (tolerance)
[character]
scalar. Optional user-defined message. Must
be a single character string. Multiline comments may be separated by
"\n"
.
passed on to grepl
(useful for e.g. fixed=TRUE
).
[logical]
suppress output printed by the current
expression (see examples)
[character]
For condition signals (error, warning, message)
the class from which the condition should inherit.
[character]
A regular expression to match the message.
[logical]
scalar. If set to TRUE
, any exception
worse than the wanted exception will cause the test to fail.
An overview of tinytest can be found in vignette("using_tinytest")
.
Examples of how tinytest is used in practice can be found in
vignette("tinytest_examples")
expect_equivalent
calls expect_equal
with the extra
arguments check.attributes=FALSE
and use.names=FALSE
expect_silent
fails when an error or warning is thrown.
expect_inherits
fails when inherits(current,class)
returns FALSE
expect_stdout
Expects that output is written to stdout
,
for example using cat
or print
. Use pattern
to
specify a regular expression matching the output.

expect_equal_to_reference()
,
expect_length()
