Output is truncated when using --json and --output together

[lepapareil]

What is the current bug behavior?

When I execute Hurl over multiple files with --json and --output options I only get the last file output instead of all outputs.

• Create test1.hurl and test2.hurl :

GET https://hurl.dev
HTTP 200

• with only --json, I get all files output:

$ hurl test1.hurl test2.hurl --json | jq .filename
"test1.hurl"
"test2.hurl"

• with --json and --output I only get the last file:

$ hurl test1.hurl test2.hurl --json --output /tmp/output.json ; jq .filename /tmp/output.json
"test2.hurl"

What is the expected correct behavior ?

$ hurl test1.hurl test2.hurl --json --output /tmp/output.json ; jq .filename /tmp/output.json
"test1.hurl"
"test2.hurl"

Execution context

• Hurl Version : 4.3.0

Not specific to --json, $ hurl test1.hurl test2.hurl --output /tmp/output.txt writes only with the response of test2.hurl. I suspect that the --output file is created with "w" and not "a" (the file is created everytime instead of appended).
