(devel/R-testthat) Updated 3.1.4 to 3.1.5

# testthat 3.1.5

* Deprecation warnings are no longer captured by `expect_warning(code, NA)`,
  `expect_no_warning(code)`, or `expect_silent(code)`. This ensures that they
  bubble up to the top level so that you can address them (#1680). If you want
  to assert that code does not throw a deprecation warning, use
  `expect_no_condition(code(), class = "lifecycle_warning_deprecation")`.

* New experimental `expect_no_error()`, `expect_no_warning()`,
  `expect_no_message()`, and `expect_no_condition()` for asserting
  the code runs without an error, warning, message, or condition (#1679).

* Fixed a warning in R >=4.2.0 on Windows that occurred when using the C++
  testing infrastructure that testthat provides (#1672).

* Fixed an issue that could prevent compilation of Catch unit tests with
  LLVM 15. In the interim, packages needing a local workaround can set
  `PKG_CPPFLAGS = -DCATCH_CONFIG_CPP11_NO_SHUFFLE` in their `src/Makevars`.
  (@kevinushey, #1687)

* Improve way `capture_output()` handles encoding thanks to suggestion from
  Kurt Hornik (#1693). This means that snapshots using UTF-8 encoded text on
  windows work once again.

* `local_reproducible_output()` will no longer attempt to set the local language
  when `LANG='C'` is set or an R version is used that was not compiled with
  natural language support (NLS), which would previously emit non-test-related
  warnings during testing (@dgkf, #1662; @heavywatal, #1689).

* `test_check()` now suppresses hyperlinks since they'll take you to the wrong
  places (#1648).

* New `set_max_fails()` helper to make it easier to set the maximum number of
  failures before stopping the test suite. And the advice to set to Inf is
  now clickable (#1628).

* You can now configure the behaviour of the implicit
  `devtools::load_all()` call performed by `devtools::test()` in your
  package DESCRIPTION file (#1636). To disable exports of internal
  functions and of testthat helpers, use:

  ```
  Config/testthat/load-all: list(export_all = FALSE, helpers = FALSE)
  ```

  Helpers are now attached on the search path by default after calling
  `devtools::test()`.
