tinytest 1.4.2

• expect_condition now uses conditionMessage internally. This should increase compatibility with packages defining custom conditions. (thanks to Tim Taylor for suggesting and Etienne Bacher for reporting)
• expect_match is now available when testing packages (thanks to Tim Taylor for the PR and Marcel Ramos for reporting)
• fix in pattern matching for warnings (thanks for Matthijs Berends for the PR)
• Fixed exit_if_not() that would always exit (thanks to Vincent Arel-Bundock for reporting)

tinytest 1.4.1 (2023-02-21)

• expect_warning and expect_message gain argument 'strict'. This toggles between failing when an exception worse than the expected one is thrown. (Thanks to Joshua Ulrich for the suggestion)
• New function 'expect_length' checks length of object (thanks to Marcel Ramos for suggesting).
• New function 'exit_if': conditionally exit a test file, akin to stopifnot. (Thanks to Grant McDermott for triggering this).
• New function 'expect_match' to test whether string output(s) match a regular expression (Thanks to Aaron Jacobs for the suggestion).
• package has no logo now, thanks to Reto Stauffer!
• 'build_install_test' gains 'color' argument (thanks to Tim Taylor for suggesting)
• 'run_test_file' and 'build_install_test' gain 'encoding' argument that is passed to 'parse' for reading test files (thanks to Vincent Goulet for suggesting).
• exit_file() is now safeguarded against non-character argument.
• Fixed reporting issue for class labels on conditions. (thanks to dherz for reporting)
• Fixed bug: multiple extension packages are now possible (thanks to Vincent Arel-Bundock for the PR)

tinytest 1.3.1 (2021-07-06)

• expect_error, _warning, _message, _stdout now accept ... arguments that are passed as extra arguments to 'grepl', when a pattern is provided (Thanks to Bart-Jan van Rossum for the GH issue).
• Package now also resets locale settings after each file run, and 'report_side_effects' also tracks changes in locale settings.
• Run test directories via RStudio addin. (Thanks to Matthijs Berends for PR #83)
• tinytest used to implicitly depend on R >= 3.2.0 because of using 'trimws' and 'dir.exists'. (Thanks to Sebastian Meyer for figuring this out and thanks to Matthijs Berends for PR #84 solving this)
• 'tinytest' objects now store the stack trace as a list of calls. When needed, the relevant part of the trace is printed, but only when printing the long form. (thanks to Jonas Kristoffer Lindeloef for suggesting)
• Improved printing while running tests
• Graphics produced in tests are now written to nullfile() (Thanks to Henrik Bengtsson for the suggestion). (nullfile() is defined in-package when built on R < 3.6.0).
• Fixed time measurement when directory (or pkg) is tested and tests take more than an minute.
• Fix: set_env variables would not be unset in all cases (Thanks to Henrik Bengtsson for the PR)
• Fix in 'expect_equal': reporting in case of differing attributes (Thanks to Ott Toomet for reporting #80).
• Fix in build_install_test: better reading of DESCRIPTION file (Thanks to Christof Stepper for PR #87)

tinytest 1.2.4 (2020-12-17)

• 'test_package' gains 'lib.loc' argument.
• New function 'expect_inherits' to check the class of an object (thanks to Sebastian Meyer for suggesting).
• Printing of file exit message is now shorter and on same line as test report (thanks for Dirk Eddelbuettel for suggesting).

• Small improvements in difference reporting.
• Fix: avoid truncated printing in case of long diff reporting (thanks to Sebastian Meyer for the PR)
• Fix: default pattern for test files was "^test_", is now "^test" as documented. (Thanks to Sebastian Meyer for the PR).
• Fix: it is now easier to put tests that you do not want to install under /tests/somedir.
• Internal: updated tinytest.format method to conform to new R CMD check demand. (Thanks to Brian Ripley for the warning).

tinytest 1.2.3 (2020-10-07)

• Added example to using tinytest vignette on mocking databases (Thanks to Thomas Fuchs for working this out).
• 'expect_stdout' now handles multi-line output. (Thanks to John Blischak for reporting).

• New function 'expect_stdout' compares output of e.g. 'print' and 'cat' statements to a user-defined pattern. (Thanks to Michel Lang for suggesting).
• New function get_call_wd() returns working directory, active when tests were invoked. (Thanks to Maja Zaloznik for the idea)
• Functions 'expect_error', 'expect_warning', and 'expect_message' gain 'class' argument, that can be used to check whether a signaling condition inherits from a certain class. (thanks to Michel Lang for suggesting)
• Argument 'tol' now renamed 'tolerance'. Also removed internal reliance on partial argument matching (Thanks to Michel Lang).
• Updated documentation on how to extend tinytest with new recommendation.
• Using tinytest vignette gains section on testing internal functions.
• Breaking: function 'expect_message' no longer intercepts messages sent to stdout (e.g. via 'print' or 'cat'), but only messages send as a 'message' condition (Thanks to Michel Lang for pointing this out).
• Fix: 'test_package' would return NULL when called interactively and the package contained a failing test.

tinytest 1.1.0 (2019-09-26)

tinytest 1.0.0 (2019-08-23)

• New argument 'side_effects' for test runners: monitor side effects while running tests.
• New function 'report_side_effects': toggle monitoring side-effects within test files.
• Run test files in parallel, for example: test_package("pkg", ncpu=2). (Thanks to Dirk Eddelbuettel for the suggestion).
• New function 'exit_file': stop running a test file with an optional message.
• Other packages can now extend the package, see '?register_tinytest_extension' for the API (Thanks to Michel Lang for the suggestion)
• New function 'using' loads tinytest extension package.

• New function 'expect_message'.
• New functions 'all_pass', 'all_fail', 'any_pass', 'any_fail' for investigating 'tinytests' objects.
• When ‘interactive()', ’test_package' will not throw an error upon a failing test. Still throws an error when not 'interactive()'. This makes it more usefull for interactive testing of installed packages.
• 'test_package()' now returns a 'tinytests' object.
• Better 'verbosity' while running test files (thanks to Dirk Eddelbuettel for discussions and feedback)
• Added 'test_silent'. Check for lack of errors or warnings (Thanks to Bryan Hanson for the suggestion, #14)
• Colored output is turned off automatically when the pkg is loaded in a "dumb" terminal. (Thanks to Dirk Eddelbeutel for the suggestion, #12).
• Improved documentation, including on how to skip tests on CRAN.
• Improved vignette layout (thanks to Dirk Eddelbuettel's suggestions and initial PR #15 for geometry settings)
• Improved behavior of 'setup_tinytest()' when a 'Suggests' field is already present in DESCRIPTION
• Fix: toleracence was not passed to 'all.equal' by 'expect_equal' and 'expect_equivalent' (Thanks to An Chu #17)
• Fix 'expect_warning' and 'expect_error' would crash when run on the CLI. (Thanks to Bryan Hanson #13)
• Fix: method dispatch in packages defining S4 methods now works.
• Fix: 'setup' now adds 'tinytest' to 'Suggests:' rather then adding an extra 'Suggests' field in DESCRIPTION.
• Corrections in README and vignette, thanks to GH user 'salim-b' PR #18, #19
• Internal: simplified code for 'expect_warning' and 'expect_error' (thanks to Lionel Henry for suggestions).

tinytest 0.9.4 (2019-06-05)

• New function 'setup_tinytest' that adds 'tinytest' infrastructure to a package source directory.
• Global settings set by 'options' and 'Sys.setenv' in a test file are automatically removed after running a test file. This improves independence between test files. This default can be overwritten, see Chapter 3 of the 'Using tinytest' vignette.
• Test file sorting order can be controlled with 'lc_collate' option in test runners or by setting options(tt.collate) globally.
• More control over testing packages in 'R CMD check' with extra arguments to 'test_packages'.
• Improved call reporting in case of multiline test expressions (for example when many test expressions depend on an 'if' condition).
• Fix in 'expect_warning' and 'expect_error'. In some circumstances evaluation argument 'current' evaluated in the wrong scope, resulting in unfound variables.

tinytest 0.9.3 (2019-05-10)

• New function 'expect_identical'
• All functions of the form 'expect_lol' can now also be called as 'checkLol' (similar to, but not the same as 'RUnit' syntax)
