# 1 EUnit Release Notes

This document describes the changes made to the EUnit application.

### 1.1 Eunit 2.2.3

#### Fixed Bugs and Malfunctions

- New option 'no_tty' to silent the default tty report.

  Recognize the new stacktrace format introduced in R15, adding location information. (Thanks to Klas Johansson.)

  Improve layout of error messages, printing the stack trace before the error term.

  Heuristically detect and report bad return values from generators and instantiators. E.g., "ok" will not be interpreted as a module name, and a warning will be printed.

  New test representation {test,M,F} for completeness along with {generator,M,F}. Tuples {M,F} are deprecated.

  Use UTF-8 as encoding in Surefire output files. (Thanks to Lukas Larsson.)

### 1.2 Eunit 2.2.2

#### Improvements and New Features

- Erlang/OTP can now be built using parallel make if you limit the number of jobs, for instance using 'make -j6' or 'make -j10'. 'make -j' does not work at the moment because of some missing dependencies.

  Own Id: OTP-9451

### 1.3 Eunit 2.2.1

#### Fixed Bugs and Malfunctions

- Generate separate surefire XMLs for each test suite

  Previously the test cases of all test suites (=modules) were put in one and the same surefire report XML thereby breaking the principle of least astonishment and making post analysis harder. Assume the following layout:

  src/x.erl src/y.erl test/x_tests.erl test/y_tests.erl

  The results for both x_tests and y_tests were written to only one report grouped under either module x or y (seemingly randomly).

  Now two reports, one for module x and one for y are generated. (Thanks to Klas Johansson)

- Updated to EUnit version 2.2.0

  New macros assertNotMatch(Guard, Expr), assertNotEqual(Unexpected, Expr), and assertNotException(Class, Term, Expr).

  The debugMsg macro now also prints the pid of the current process.

  When testing all modules in a directory, tests in Module_tests.erl are no longer executed twice.

  The use of regexp internally has been replaced with re. (Thanks to Richard Carlsson)

  Own Id: OTP-9505

- Removed some never-matching clauses reported by dialyzer Updated author e-mails and homepages Removed cvs keywords from files Removed files that should not be checked in (Thanks to Richard Carlsson)

### 1.4 Eunit 2.1.7

#### Fixed Bugs and Malfunctions

- Increase depth of error messages in Eunit Surefire reports

  Currently, error messages in Eunit Surefire reports are shortened just like when written to a terminal. However, the space limitations that constrain terminal output do not apply here, so it's more useful to include more of the error message. The new depth of 100 should be enough for most cases, while protecting against runaway errors. (Thanks to Magnus Henoch)

- Don't let eunit_surefire report back to eunit when stopping

  When eunit is terminating, a stop message is sent to all listeners and eunit then waits for *one* result message but previously both eunit_tty and eunit_surefire sent a response on error. Don't send a result message from eunit_surefire; let eunit_tty take care of all result reporting, both positive and negative to avoid race conditions and inconsistencies. (Thanks to Klas Johansson)

### 1.5 Eunit 2.1.6

#### Fixed Bugs and Malfunctions

- Fix format_man_pages so it handles all man sections and remove warnings/errors in various man pages.

  Own Id: OTP-8600

### 1.6 Eunit 2.1.5

#### Improvements and New Features

- The documentation is now possible to build in an open source environment after a number of bugs are fixed and some features are added in the documentation build process.

  - The arity calculation is updated.

  - The module prefix used in the function names for bif's are removed in the generated links so the links will look like "http://www.erlang.org/doc/man/erlang.html#append_element-2" instead of "http://www.erlang.org/doc/man/erlang.html#erlang:append_element-2".

  - Enhanced the menu positioning in the html documentation when a new page is loaded.

  - A number of corrections in the generation of man pages (thanks to Sergei Golovan)

  - The legal notice is taken from the xml book file so OTP's build process can be used for non OTP applications.

### 1.7 Eunit 2.1.4

#### Improvements and New Features

- The documentation is now built with open source tools (xsltproc and fop) that exists on most platforms. One visible change is that the frames are removed.

### 1.8 Eunit 2.1.3

#### Improvements and New Features

- Miscellaneous updates.

  Own Id: OTP-8190

### 1.9 Eunit 2.1.2

#### Improvements and New Features

- Miscellanous updates.

  Own Id: OTP-8038

### 1.10 Eunit 2.1.1

#### Fixed Bugs and Malfunctions

- eunit was broken in R13B.

  Own Id: OTP-8018

### 1.11 Eunit 2.1

#### Improvements and New Features

- Mostly internal changes, in particular to the event protocol; fixes problems with timeouts that could cause eunit to hang, and makes it much easier to write new reporting back-ends.

  New "surefire" report backend for Maven and Bamboo.

  The test representation is no longer traversed twice (the first pass was for enumeration only). This eliminates some strange restrictions on how generators can be written, but it also means that reports cannot be quite as complete as before in the event of skipped tests.

### 1.12 EUnit 2.0.1

#### Improvements and New Features

- Corrected the documentation build.

### 1.13 EUnit 2.0

#### Improvements and New Features

- This is the first version of EUnit (for unit testing of Erlang modules) by Richard Carlsson released in OTP.
