Announcing Hurl 4.1.0

The Hurl team is happy to announce Hurl 4.1.0 Rocket !

Hurl is a command line tool powered by curl, that runs HTTP requests defined in a simple plain text format:


HTTP 200
header "x-foo" contains "bar"
certificate "Expire-Date" daysAfterNow > 15
jsonpath "$.status" == "RUNNING"    # Check the status code
jsonpath "$.tests" count == 25      # Check the number of items
jsonpath "$.id" matches /\d{4}/     # Check the format of the id

What’s new in this release:

TAP Report

We’ve added a new test report: TAP, the Test Anything Protocol. TAP is a simple text-based interface between testing modules in a test harness. With HTML report and JUnit report, Hurl supports now TAP report.

Let’s say we run some tests. We can use --report-tap REPORT-FILE option to set the report TAP file. If the report file exists, results will be appended to it.

$ hurl --test --report-tap report.txt *.hurl
add-favorite.hurl: Running [1/6]
add-favorite.hurl: Success (7 request(s) in 5516 ms)
basic.hurl: Running [2/6]
basic.hurl: Success (7 request(s) in 1537 ms)
csrf.hurl: Running [3/6]
error: Assert status code
  --> csrf.hurl:3:6
 3 | HTTP 301
   |      ^^^ actual value is <200>

csrf.hurl: Failure (2 request(s) in 5527 ms)
login.hurl: Running [4/6]
login.hurl: Success (3 request(s) in 3091 ms)
perf.hurl: Running [5/6]
perf.hurl: Success (4 request(s) in 1317 ms)
security.hurl: Running [6/6]
security.hurl: Success (5 request(s) in 2278 ms)
write tap report report.txt
Executed files:  6
Succeeded files: 5 (83.3%)
Failed files:    1 (16.7%)
Duration:        19304 ms

Then, we can see what our TAP report looks like:

$ cat report.txt
ok 1 - add-favorite.hurl
ok 2 - basic.hurl
not ok 3 - csrf.hurl
ok 4 - login.hurl
ok 5 - perf.hurl
ok 6 - security.hurl

Simple and neat! TAP has wide support across many language and there are many tools that can convert TAP to other formats, so it’s a nice addition to Hurl!

Add Delay Between Requests

With the new --delay option, you can add a delay between requests:

$ hurl --delay 2000 --test *.hurl

This command add a 2 seconds delay between each request. As with a lot of Hurl command line options, you can specify a delay for a single request, with an [Options] section, without impacting other requests:

HTTP 200

# This next request will be runned 5s after the
# first one
delay: 5000
HTTP 200

--connect-to and --resolve per Request Option

Speaking of [Options] sections, --connect-to and --resolve can now be specified per request:

HTTP 200

# --resolve option allow to us custom address for a specific host and port pair.
HTTP 200

As of Hurl 4.1.0, the [Options] section supports:

# An options section, each option is optional and applied only to this request...
aws-sigv4: aws:amz:sts  # generate AWS SigV4 Authorization header
cacert: /etc/cert.pem   # a custom certificate file
compressed: true        # request a compressed response
insecure: true          # allows insecure SSL connections and transfers
location: true          # follow redirection for this request
max-redirs: 10          # maximum number of redirections
path-as-is: true        # tell curl to not handle sequences of /../ or /./ in the given URL path
variable: country=Italy # define variable country
variable: planet=Earth  # define variable planet
verbose: true           # allow verbose output
very-verbose: true      # allow more verbose output

If you need an Hurl command line option (which make sense for a single request) to be on this list, don’t hesitate to fill an issue!

AWS Signature Version 4

Every interaction with Amazon S3 is either authenticated or anonymous. Authenticating to AWS is done through AWS Signature Version 4. With --aws-sigv4, you can use AWS Signature Version 4 to authenticate your requests

$ hurl --user someAccessKeyId:someSecretKey \
 --aws-sigv4 aws:amz:eu-central-1:foo \

And of course, --aws-sigv4 can be specified for a single request:

aws-sigv4: aws:amz:eu-central-1:foo
HTTP 200

ARM 64 bits Docker Image

Hurl can be installed as a native binary on a large number of platforms. We also provide a Docker image. Since 4.1.0, Hurl Docker’s image is a multi-arch build: along x86 architectures, the image supports now ARM 64 bits targets such as Raspberry Pis, AWS A1 instances or even ARM’s Apple computers.

$ docker run -v /tmp/:/tmp/ --test example.hurl
example.hurl: Running [1/1]
example.hurl: Success (1 request(s) in 190 ms)
Executed files:  1
Succeeded files: 1 (100.0%)
Failed files:    0 (0.0%)
Duration:        193 ms


Changes that require a particular attention:

  • we have renamed --fail-at-end option to --continue-on-error as the latter is more understandable
  • we have fixed --path-as-is option name (instead of --path_as_is)

There are other improvements and bug fixes, you can check a complete list in our release note. If you like Hurl, don’t hesitate to give us a star on GitHub or share it on Twitter / X!

We’ll be happy to hear from you, either for enhancement requests or for sharing your success story using Hurl!
