vcr 1.6.0
CRAN release: 2024-07-23
NEW FEATURES
-
vcr
now supportshttr2
in addition tohttr
andcrul
. (#237) (#268) -
vcr
now supports async http requests withcrul
(w/crul
v1.5 or greater). no change was required invcr
for this to happen. a PR was merged incrul
to hook intovcr
. there’s no support for async inhttr
as that package does not do any async and no support inhttr2
becausereq_perform_parallel
does not have a mocking hook as doesreq_perform
(#246)
vcr 1.2.0
CRAN release: 2022-11-17
MINOR IMPROVEMENTS
-
use_vcr()
now creates a test helper file calledhelper-vcr.R
instead ofsetup-pkgname.R
. We are reverting the change from version 0.6.0 and now recommend the use ofhelper-*.R
again, so that the vcr setup is loaded withdevtools::load_all()
. That way your vcr-enabled tests also work when run interactively (#244) (#256) - default git branch changed from master to main (#253)
- update example packages in the README (#257)
- vcr no longer requires compilation because replaced the single C++ function with a pure R equivalent
vcr 1.1.0
CRAN release: 2022-11-04
MINOR IMPROVEMENTS
- request matching was sensitive to escaping special characters, that’s been fixed (#240) (#247) thanks to @KevCaz
- fix broken link given in error suggestion (#239) thanks to @maelle
- using
preserve_exact_body_bytes = TRUE
now writes a base64 encoded string into a field in yaml or json on disk calledbase64_string
. Whenpreserve_exact_body_bytes = FALSE
(the default) the response body goes into a field calledstring
vcr 1.0.2
CRAN release: 2021-05-31
BUG FIXES
- fix to
vcr_test_path()
to find root package path correctly (#235) (#236)
vcr 1.0.0
CRAN release: 2021-05-22
NEW FEATURES
-
check_cassette_names()
gainsallowed_duplicates
parameter to allow duplicate cassette names; we typically advise users not to use duplicate cassette names, but there are cases where you may want to share cassettes across tests (#227) -
vcr_configure()
gainsfilter_query_parameters
parameter for filtering out query parameters so they don’t show up in the recorded request on disk (#212) -
use_vcr()
: now sets a mimimum vcr version, which is usually the latest (stable) version on CRAN. You can of course easily remove or change the version requirement yourself after running it (#214) -
vcr_configure()
gainswarn_on_empty_cassette
parameter: Should a warning be thrown when an empty cassette is detected? Empty cassettes are cleaned up (deleted) either way (#224) thanks @llrs and @dpprdan -
vcr_configure()
gainsquiet
parameter: suppress any messages from both vcr and webmockr (#226) (#25) -
vcr_configure()
gains new optionfilter_sensitive_data_regex
; nowfilter_sensitive_data
is for fixed string matching, whilefilter_sensitive_data_regex
is for regex based matching (#222) thanks @tomsing1 for reporting - gains package import
rprojroot
MINOR IMPROVEMENTS
-
filter_sensitive_data
option now strips leading and trailing single and double quotes from strings before being used IN CASE a user accidentally quotes a secret - logic being that even though a secret may have a single or double quote in it, its very unlikely that it would have both a leading and trailing quote (single or double) (#221)
Documentation
- new vignette explaining the design of the vcr package (also can be found in the HTTP Testing book) (#232) (#233)
- no user facing change - but vignettes moved into man/rmdhunks so that they can be pulled into the HTTP Testing book easily (#209) (#216)
- fix in configuration vignette to clarify a
filter_request_headers
example (#215) thanks @maelle - docs update (#33) (#217)
BUG FIXES
-
filter_request_headers
was unfortunately adding a request header to the request written to disk when the header did not exist; now fixed (#213) - bug in internal function
is_base64()
;strsplit()
neededuseBytes=TRUE
(#219) -
filter_sensitive_data
was not working when strings contained regex characters; fixed, and see also above new config variable for regex specific filtering (#222) thanks @tomsing1 for reporting -
vcr_test_path()
should now correctly set paths (#225) (#228) (#229) (#230)
vcr 0.6.0
CRAN release: 2020-12-12
NEW FEATURES
- We have a new vcr contributor! @maelle (#198)
- Gains a new serializer: JSON. You can use this serializer by setting globally
vcr_configure(serialize_with="json")
or per cassetteuse_cassette(..., serialize_with="json")
. The JSON serializer usesjsonlite
under the hood. Note that we by default do not write JSON to disk preserving newlines; that is the JSON is all on one line. You can use pretty printing by settingjson_pretty
invcr_configure()
. As part of this change, factored out new R6 classSerializer
from which both JSON and YAML serializers inherit (#32) - Gains two new configuration options for managing secrets:
filter_request_headers
andfilter_response_headers
. These are implemented differently thanfilter_sensitive_data
. The two new filters do simple value replacement or complete removal of request or response headers, whereasfilter_sensitive_data
uses regex to replace strings anywhere in the stored request/response. See the “Configure vcr” vignette for details (#182) - request matching:
host
andpath
now work (#177) (see also #70) - In previous versions of vcr the
insert_cassette()
/eject_cassette()
workflow did not work because the webmockr triggers required only worked when usinguse_cassette()
. This has been fixed now so you can useuse_cassette()
, passing a code block to it, or runinsert_cassette()
then run any code, then when finished runeject_cassette()
. (#24) thanks @Robsteranium for the nudge, may not have fixed this without it - improve debugging experience: new vignette “Debugging your tests that use vcr”, including new function
vcr_test_path()
- which is now used inuse_vcr()
so that the correct path to tests is used when running tests both interactively and non-interactively (#192) (#193) - Dependencies: dropped
lazyeval
from Imports;withr
added to Suggests; minimumwebmockr
version nowv0.7.4
- In README, point to rOpenSci code of conduct rather than file in repo
- Gains function
skip_if_vcr_off()
to use in tests to skip a test if vcr is turned off (#191) (#195)
MINOR IMPROVEMENTS
- slight factor out of some code in YAML serializer to use elsewhere (#203) (#204)
- serializers: drop
$deserialize_string()
method as was not used - rename$deserialize_path()
method to just$deserialize()
(#189) - serializers: with the new JSON serializer, documentation added to
?vcr_configure
and?use_cassette
stating that you can have different cassettes with the same name as long as they use different serializers (and then have different file extensions). if you want to change serializers but do not want to keep the old cassette with the old serializer make sure to clean up the old file (#188) - now using GitHub Actions - remove Travis-CI and Appveyor (#175)
- fixes for tests not being idempotent (#174) thanks @alex-gable
- clean up
UnhandledHTTPRequestError
- remove unused variablecassette
in$initialize()
method (always usecurrent_cassette()
to get the cassette being used) (#163) tip from @aaronwolen - A change in latest webmockr release (
v0.7.4
) allowed for changes here to return an httrresponse
object that more closely matches what httr returns in a real HTTP request. Before this the major problem was, assumingx
is a httrresponse
object,x$request
was aRequestSignature
object (fromwebmockr
), whereas the class in a real httr response object isrequest
(#132) - Re-factor of
Cassette
class greatly simplifying webmockr HTTP request stubbing (#98) (#173) big thanks to @alex-gable ! -
HTTPInteractionList
improvement: in checking for request matches against those on disk we were checking all requesets in a cassette - faster to check and stop when a match found. Using new factored out function to do this checking that stops when first match found. Many more tests added to check this behavior (#69) - base64 encoded output in cassettes when using YAML serializer are now wrapped to approximately 80 character width (triggered when
preserve_exact_body_bytes=TRUE
) - this makes cassettes longer however. Implementing this brought in use ofcpp11
(first use of C++ in vcr). This makes base64 encoded response body recording consistent with how vcr’s in other programming languages do it (#41) -
decode_compressed_response
option removed fromCassette
class - wasn’t being used and won’t be used (#30) - add additional examples to
VcrResponse
docs showing what theupdate_content_length_header()
does (#29) -
use_vcr()
changes: 1) now creates a test helper file calledsetup-pkgname.R
instead ofhelper-pkgname.R
; 2) now by default sets directory for fixtures usingdir = vcr_test_path("fixtures")
instead ofdir = "../fixtures"
. See other news item aboutvcr_test_path
DOCUMENTATION
- better description of vcr at top of README (#198)
- delete unused docs folder in repository (docs built elsewhere) (#210)
- tell users that explicitly loading vcr is required in your test setup (#185) (#186) thanks @KevCaz
- added explanation of where and how
webmockr
is integrated inCassette
class - see section “Points of webmockr integration” in?Cassette
(#176) (see also #173) - improved getting started and protecting secrets sections in the introduction vignette (#170) (#172) thanks @DaveParr
- add to introduction vignette a section titled “how to ensure tests work in the absence of a real API key” (#137) (#194)
vcr 0.5.4
CRAN release: 2020-03-31
NEW FEATURES
- Error messages when tests using vcr fail are now simpler, primarily to reduce the space error messages take up. The user can toggle whether they get the new simplified error messages or the older format more verbose messages using the
verbose_errors
setting in thevcr_configure()
function. In addition,vcr_last_error()
gives the last full error, but that doesn’t help in non-interactive mode; if in non-interactive mode, which most users will be in when running the entire test suite for a package, you can set an environment variable (VCR_VERBOSE_ERRORS
) to toggle this setting (e.g.,Sys.setenv(VCR_VERBOSE_ERRORS=TRUE); devtools::test()
) (#121) (#154)
MINOR IMPROVEMENTS
- changed
write_disk_path
handling internally to not run it throughnormalizePath
before recording it to the cassette; passing the path throughnormalizePath
was leading to the full path recorded in the cassette, which means in a package testing context that a test that uses a file on disk will (likely) only work on the machine the cassette was first created on. with relative paths in a package context, a test that has a file written on disk should now work in different testing contexts (locally, and various continuous integration platforms) (#135) (#166) - added a bit of documentation about large files created when using vcr, and how to ignore them if needed within
.Rinstignore
and/or.Rbuildignore
(#164)
vcr 0.5.0
CRAN release: 2020-03-04
NEW FEATURES
- new function
check_cassette_names
to use in yourhelper-pkgname.R
file in your test suite; it checks for duplicated cassette names only. Any use ofinsert_cassette()
(thereby, any use ofuse_cassette()
) uses a revamped version of an internal fxn that checks for an improved list of potential problems in cassette names (#116) (#159) -
use_vcr()
adds gitignore cassette diffs via the addition of agitattributes
file (#109) -
vcr_configure()
overhaul: function no longer has each setting as a parameter; rather, it has an ellipsis (...
), and internally we check parameters passed in. The documentation (?vcr_configure
) lists the details for each available parameter. Importantly, each call tovcr_configure()
now only changes the vcr settings for parameters passed in to the function; to reset all vcr settings, runvcr_configure_reset()
(#136) (#141) -
insert_cassette()
anduse_cassette()
now inherit any vcr settings set byvcr_configure()
; this wasn’t happening consistently before. Most default parameter values ininsert_cassette/use_cassette
set toNULL
, in which case they inherit from whatever values are set byvcr_configure()
, but can be overriden (#151) (#153)
MINOR IMPROVEMENTS
- define serialize, cassette, and fixture in the README (#138) (#139)
- fix
filter_sensitive_data
parameter description invcr_configure
docs (#129) - move higher up in README a brief description of what this package does (#140)
- import
utils::getParseData
so its in namespace (#142) - better cleanup of some stray test files left on disk (#148)
-
use_vcr()
no longer usescontext()
in example test file (#144) - improved documentation of functions and environment variables for turning vcr on and off and when to use each of them - documentation mostly in the HTTP Testing book at https://books.ropensci.org/http-testing/lightswitch.html (#131)
- fix a
use_cassette
test (#133) - Add assertions to
vcr_configure()
when parameters are set by the user to fail early (#156)
BUG FIXES
- fix for handling of http requests that request image data AND do not write that data to disk; in addition, fix usage of
preserve_exact_body_bytes
when image data is in the response body (#128) thanks @Rekyt - vcr now should handle request bodies correctly on POST requests (#143)
- Request matching was failing for empty bodies when “body” was one of the matchers (#157) (#161)
- fix to
sensitive_remove()
internal function used when the user setsfilter_sensitive_data
invcr_configure()
; when an env var is missing in thefilter_sensitive_data
list,sensitive_remove()
was causing C stack errors in some cases (#160) thanks @zachary-foster - fix for recording JSON-encoded bodies; vcr wasn’t handling HTTP requests when the user set the body to be encoded as JSON (e.g.,
encode="json"
with crul or httr) (#130)
vcr 0.4.0
CRAN release: 2019-12-07
NEW FEATURES
- vcr now can handle requests from both
crul
andhttr
that write to disk;crul
supports this with thedisk
parameter andhttr
through thewrite_disk()
function; see the section on mocking writing to disk in the http testing book https://books.ropensci.org/http-testing/vcr-usage.html#vcr-disk; also see?mocking-disk-writing
withinwebmockr
for mocking writing to disk without usingvcr
, and the section in the http testing book https://books.ropensci.org/http-testing/webmockr-stubs.html#webmockr-disk (#81) (#125) - vcr gains ability to completely turn off vcr for your test suite even if you’re using
vcr::use_cassette
/vcr::insert_cassette
; this is helpful if you want to run tests both with and without vcr; workflows are supported both for setting env vars on the command line as well as working interactively within R; see?lightswitch
for details (#37) - ignoring requests now works, with some caveats: it only works for now with
crul
(nothttr
), and works for ignoring specifc hosts, and localhosts, but not for custom callbacks. See the vcr configuration vignette https://docs.ropensci.org/vcr/articles/configuration.html#ignoring-some-requests for discussion and examples (#127)
BUG FIXES
- fix handling of http response bodies that are images; we were converting raw class bodies into character, which was causing images to error, which can’t be converted to character; we now check if a body can be converted to character or not and if not, leave it as is (#112) (#119) thanks @Rekyt for the report
- simple auth with package
httr
wasn’t working (htrr::authenticate()
); we were not capturing use ofauthenticate
; it’s been solved now (#113) - we were not properly capturing request bodies with package
httr
requests; that’s been fixed (#122) - httr adapter was failing on second run, reading a cached response. fixed now (#124)
-
response_summary()
fixed; this function prints a summary of the http response body; sometimes this function would fail with multibyte string error because thegsub
call would change the encoding, then would fail on thesubstring
call; we now setuseBytes = TRUE
in thegsub
call to avoid this problem (#126)
vcr 0.3.0
CRAN release: 2019-08-20
NEW FEATURES
- new internal method
up_to_date_interactions
incassette_class
now allows filtering cassettes by user specified date (#96) (#104) - re-recording now works - see new
use_casette()
parametersre_record_interval
andclean_outdated_http_interactions
; you can now set a re-record interval (in seconds) so that you can for example always re-record cassettes if you don’t want cassettes to be more than X days old; depends on new internal methodup_to_date_interactions
(#104) (#105)
BUG FIXES
- fix request body matching - partly through fixes to
webmockr
package (requires v0.4 or greater); more generally, makes single type request matching (e.g., just HTTP method, or just URL) possible, it was not working before, but is now working; added examples of doing single type matching (#70) (#76) (#108) - fixed type in
cassette_class
where typo lead to not setting headers correctly in thewebmockr::wi_th()
call (#107)
vcr 0.2.6
CRAN release: 2019-02-12
NEW FEATURES
- gains function
use_vcr()
to setupvcr
for your package. This requires 3 pkgs all in Suggests; so are not required if you don’t need to useuse_vcr()
(#52) (#95) thanks @maelle for the feedback! -
vcr
actually supports all four recording modes:none
,once
,new_episodes
, andall
.once
is what’s used by default. See?recording
for description of the recording modes. For now the test file test-ause_cassette_record_modes.R gives some examples and what to expect for each record mode; in the future the http testing book will have much more information in the Record modes chapter https://books.ropensci.org/http-testing/record-modes.html (commit)
MINOR IMPROVEMENTS
- lots of tidying for better/consistent style
- fix for a partial argument call in
as.list()
:all
toall.names
BUG FIXES
- error thrown with
httr
due to wrong date format. the problem was in thewebmockr
package. see ropensci/webmockr#58 (#91) thanks @Bisaloo - fix for
use_cassette()
when usinghttr
: we weren’t collectingstatus_code
and storing it with the cassette (#92) thanks @Bisaloo - fixes for
use_cassette()
forhttr
: was working fine with a single httr request, but not with 2 or more (#93) (#94) thanks @Rekyt - in error blocks with
use_cassette()
the URL is presented from the request, and if there’s a secret (API key) in the URL as a query parameter (or in any other place in the URL) then that secret is shown to the world (including if the error block happens on CI on the public web). This is fixed now; we use directives from yourfilter_sensitive_data
call invcr_configure()
to mask secrets in error messages (#89) (#90)
vcr 0.2.2
CRAN release: 2019-01-13
MINOR IMPROVEMENTS
- typo fixes (#85) thanks @Rekyt
- added to docs: at least one person has reported different results using
vcr
withdevtools::check
vs.devtools::test
(#83) - changed suggested usage of
vcr
in test suites fromuse_cassette
block wrapped intest_that
to the other way around; leads totestthat
pointing to the actual test line that failed rather than pointing to the start of theuse_cassette
block (#86)
BUG FIXES
- Fix for
%||%
internal function. Was incorrectly doing logical comparison; when headers list was passed one or more of the tests in the if statement had length > 1. Dev R is testing for this (#87)
