Use `nasm-t.py -h` command to get the detailed description of every option.
+### Test unit structure
+Each test consists at least of three files:
+
+ - a test descriptor in with `*.json` extension;
+ - a source file to compile;
+ - a target file to compare result with, it is assumed to have
+ the same name as output generated during the pass file but with `*.t`
+ extension; thus if a test generates `*.bin` file the appropriate target
+ should have `*.bin.t` name.
+
+Running tests
+-------------
+To run all currently available tests simply type the following
+
+```console
+python3 travis/nasm-t.py run
+```
+
+By default the `nasm-t.py` scans `test` subdirectory for `*.json` files and
+consider each as a test descriptor. Then every test is executed sequentially.
+If the descriptor can not be parsed it silently ignored.
+
+To run a particular test provide the test name, for example
+
+```console
+python3 travis/nasm-t.py list
+...
+./travis/test/utf Test __utf__ helpers
+./travis/test/utf Test errors in __utf__ helpers
+...
+python3 travis/nasm-t.py run -t ./travis/test/utf
+```
+
+Test name duplicates in the listing above means that the descriptor
+carries several tests with same name but different options.

Test descriptor file

itself and which output files or streams to compare with predefined ones.
