expect_deprecated

expect_defunct

These functions are equivalent to <code><a href="https://testthat.r-lib.org/reference/expect_error.html">testthat::expect_warning()</a></code> and
<code><a href="https://testthat.r-lib.org/reference/expect_error.html">testthat::expect_error()</a></code> but check specifically for lifecycle
warnings or errors.
To test whether a deprecated feature still works without causing a
deprecation warning, set the <code>lifecycle_verbosity</code> option to
<code>"quiet"</code>.
<div class="sourceCode"></div><pre><code>test_that("feature still works", {
 withr::local_options(lifecycle_verbosity = "quiet")
 expect_true(my_deprecated_function())
})
</code></pre>
